      "body": "# Immutability on Blockchain and Proof of Existence\n\n<center>![divider](https://66.media.tumblr.com/3a1de144975373e89854084f4bc01f26/tumblr_mg9ovmrAoO1qzw1qyo1_500.gif)</center>\n\nIn the [last article](https://steemit.com/blockchain/@cryptoctave/blockchain-trilema-and-consensus-mechanisms-in-blockchain-technology)  I have explored two different consensus algorithms used in most of current blockchains out there. Proof of work and Proof of stake are used in order to provide immutability of transactions on the global ledger. The disruptive potential of blokchcian technology is so great that it can potentially change the way we keep records besides other great features. In today's article I will explore the immutability aspect of blockchain, why is it important and also explore a couple of projects that are using this . So let's dive right into it! ☕☕☕\n\n\n### Immutability on Blockchain\nBlockchains provide native immutability, feature which is integral and mandatory in each consensus mechanism. In other words, immutability is a *relative* condition that provide a proof to double spending problem and ensure each transaction gets recorded on the blockchain without being duplicated. I emphasis the word *relative* above as the immutability property is tightly coupled by the technology underneath and relates to how difficult is for something to change. Basically, Bitcoin`s Proof of work mechanism immutability could be broken by a 51% attack on the network which would require a huge amount of computation power. However, as we have seen recently in [Ethereum Classic 51% attack](https://cointelegraph.com/news/ethereum-classic-51-attack-the-reality-of-proof-of-work), immutability could be broken if the network is small and not decentralized enough.\nNevertheless, immutability is the aspect that has levereged blockchain technology as being the most disruptive technology we ever create as it provides audability for transactions without a trusted 3rd party. Given this property, can it be extended beyond transactions and also be applied to data, providing audability for documents, records, contracts etc? The answer is Yes, but let's see how. \n\n\n### Proof of Existence using Timestamp\nEvery since the first contract was ever written, people have used a delegate or a trusted third party in order to provide a level of security for their agreement. During the times these delegates have evoloved in legal bodies such as governments, notaries, law firms that confirm integrity of documents between two parties and offer a degree of trust. If you ever used one of the services offered by these bodies, you know that there is need for a signature, date(and time) and a stamp in order to validate a contract between two parties.\n\nTimestamping on blockchain works in a similar fashion, by using algorithms to create a digest, or a cryptographic string that is representative of a piece of data. The digest created by a hash function is based on the characteristics of a document. No two digests are the same, unless the data used to compute the digests is the same. The cryptographic digest is attached to a blockchain transaction linked to the time when the document was subitted. This allows you to later certify that the document/data existed at that time and publicly prove that you have certain information without revealing the data or yourself, with a decentralized certification based on the blockchain network.\n\nThe key advantages of timestamping are anonymity, privacy, and getting a decentralized proof which can't be erased or modified by anyone (third parties or governments). Your document's existence is permanently validated by the blockchain even if this site is compromised or down, so you don't depend or need to trust any central authority. All previous data timestamping solutions lack this freedom.\n\nFrom signing important documents like mortgage deeds and insurance contracts, to claiming contest winnings, to creating patents and even claiming scientific discoveries, there is no limit to the uses of this basic business functionality. Prior to the blockchain it was time and labor intensive.\n<center>![proof-of-work](https://cdn-images-1.medium.com/max/1000/0*qKGxfAPQX4ZYrlZL.png)</center>\n\n<center>![po.et](https://cdn-images-1.medium.com/max/822/1*[email protected])</center>\n### Po.et\nPo.et (POE) extends the timestamping and hashing features pioneered by Proof of Existence to enable new commercial applications by including additional metadata and discoverability. While Proof of Existence requires users to have the original file in order to verify the file’s hash and timestamp, Po.et allows for the original file and its metadata to be discoverable. This makes it possible for anyone to verify both the authenticity of the original file and the associated metadata.\nBy creating an open platform using IPFS and the Bitcoin blockchain, Po.et aims to create the most institutional, globally-verifiable record of digital media assets. This record will be a framework for building smart, interoperable media applications using a shared, standard and extensible metadata. Such potential applications to build on Po.et protocol are:\n- Put together your own search engine ranking system by picking highly trusted curators that only use high-quality content\n- Creators can invest in validating claims about their content to ensure its authenticity, originality, and subject matter in order to make more money\n- Brands can be sure that their logo is only being used against approved pieces of content\n- Find other people trying to claim your content as their own to protect your intellectual property\n- Establish a provable chain of custody for your academic paper\n\nMore information on Po.et protocol can be found in the [original whitepaper](https://uploads-ssl.webflow.com/5a0c978e0d22aa0001464356/5a7796662b07370001ace7a1_whitepaper.pdf).\n\n<center>![divider](https://cdn-images-1.medium.com/max/1000/0*qKGxfAPQX4ZYrlZL.png)</center>\n\n<center>![tierion](https://qph.fs.quoracdn.net/main-qimg-49fff82f6c677a24a46e3a55b3092f47)</center>\n### Tierion\nTierion project utilizes Bitcoin’s blockchain to verify documents by anchoring the cryptographic digest to a bitcoin transaction, in a similar fashion to Proof of Existance. At the core of Tierion’s technological infrastructure is the Chainpoint Proof protocol. The protocol comes into play when a user adds something in Tierion’s data store. Chainpoint, an open standard and Tierion’s API, anchors the data to the blockchain in order to generate a timestamp proof and  gives customers confidence in the data integrity and timestamp of information they collect from their business processes. \nChainpoint has been applied to supply chain use cases, where the tracking information, sign of approvals and inspections are important to record. Other common use cases include:\n- Creating an audit trail for a business process\n- Document timestamping\n- Securing the integrity of clinical trial data\n- Regulatory compliance\n\nWith its highly scalable architecture consisting of nodes operated by the community, Chainpoint has the ability to create million of proofs per second. It scales with more usage - with throughput increasing as nodes join the network. At the same time, it is designed to remain free or inexpensive for network participants.\n\nMore information on Tierion project can be found in the [original whitepaper](https://tokensale.tierion.com/TierionTokenSaleWhitePaper.pdf).\n\n<center>![divider](https://cdn-images-1.medium.com/max/1000/0*qKGxfAPQX4ZYrlZL.png)</center>\n\nSo, today we have explored how using the Bitcoin blockchain Proof of Existance feature, we can create audit trails for documents integrity on enterprise level or verify content ownership and discovered two important blockchain projects with unique use cases for Proof of Existence concept.\nI hope you enjoyed this post and found it useful.

This being said, I thought I should start with an introduction on consenus mechanisms, how do they work and why are they needed in blockchain technology. Since there are quite a few consensus mechanisms out there already, each with their own use case of implementation, in this article I will focus on the most common two: Proof of work and Proof of Stake. So grab a coffee ☕ and let's dive straight into it.\n\n<center>![proof-of-work](https://cdn-images-1.medium.com/max/1000/0*qKGxfAPQX4ZYrlZL.png)</center>\n\n## What is a Consensus Mechanism?\nPerhaps one of the greatest features of (most) blockchains is decentralization. In order to achieve decentralization in distributed systems, there is the need to enforce a consensus mechanism — a set of rules or instructions that tell the blockchain how to deal with new data. Consensus mechanisms enable parties involved in a transaction to come to an agreeent by giving financial rewards or punishments. They also provide a solution to double spending problem achieving reliability in a network with untrusted peers. In other words, consensus mechanisms are used in order to reach agreement on a single decision within the network. \nConsensus protocols provide two guarantees with respect to order and timing:\n* **Safety:** As long as the protocol does not have more than some threshold of faulty participants, other participants cannot convince a client to accept an incorrect or invalid message.\n* **Liveness:** As long as the protocol does not have more than some threshold of faulty participants, other participants cannot indefinitely delay the acceptance of a correct message.\n\nSafety and liveness are inseparable properties of fault-tolerant protocols. Fault tolerant protocols use techniques to guarantee liveness which affect safety and vice-versa. \n\nFor example, the consensus mechanism in blockchain technology is used in order to make sure that Alice has sent 5 coins to Bob and she is not able to use again the same coins for another transaction. This is known as the double-spend problem, and Bitcoin which was developed by Satoshi Nakamoto, is the first protocol to solve the problem.\n<center>![proof-of-work](https://cdn-images-1.medium.com/max/1000/0*qKGxfAPQX4ZYrlZL.png)</center>\n\n## Proof of Work (POW)\n<center>![proof-of-work](https://file.globalupload.io/BcHUnZ9Nsm.jpg)</center>\n\nImagine you are in a room with 9 of your mates and you are all gived 6 cards. You must use basic calculations and the available cards only once in order to achieve the set result. The first one to find an answer will get rewarded with a prize. **Simple!** Fundamentally speaking, this is Proof of Work(POW), the original consensus mechanism used in Bitcoin blockchain and developed by Satoshi Nakamoto.\n\nBut you might ask, *how about if two or more answers are found???*\nMultiple valid solutions can be found for any given puzzle. However, only one of the solution needs to be found in order for the puzzle to be solved. Bitcoin's POW uses a “longest chain wins” metric to decide on which history is the correct history. And this history should match the expected history if all nodes in the network were honest. POW is a succesful consensus mechanism due to it`s two fundamental properties:\n - First property ensures that a predefined amount of work has been invested by the party providing the proof of work.\n - Second property ensures the proof is easily verifiable.\n\nFor example, the hashing algorithm used in Bitcoin`s POW is double-SHA256 (SHA256<sup>2</sup>) and\nthe predefined structure is a hash less or equal to a target value T. The success probability PR, of finding a nonce n for a given message msg, such that H = SHA256 2(msg||n) is less or equal to the target T is:\n<center>**Pr[H ≤ T] = T / 2<sup>256</sup>**</center>\nThis will require a party attempting to find a proof of work to perform on average, the following amount of computations:\n<center>**1 / Pr[H ≤ T] = 2<sup>256</sup> / T**</center>\n \nMultiple valid solutions can be found for any given block. However, only one of the solution needs to be found in order for the puzzle to be solved. Finding solutions to a proof of work puzzle is a probabilistic process with the success of probability defined by the amount of computation available and a predefined difficulty. In other words, the more computation power, the higher hash rate which results in a higher profit from mining. The following parameters are used in order to calculate the profit: \n- Difficulty factor\n- Hash Rate (TH/s)\n- BTC/USD Exchange rate\n- Pool Fees in %\n- Hardware cost in USD\n- Power watts\n- Power cost (USD/kWh)\n\nIn Proof of work consensus algorithm, the more power the mining hardware consumes, the higher the hash rate. This results in a higher profit from mining.[1]\n*See [\"Is Bitcoin Mining Profitable in 2018\" ](https://99bitcoins.com/bitcoin-mining/) - Ofir Beigel, 99Bitcoins, 2018.*\n<center>![proof-of-work](https://cdn-images-1.medium.com/max/1000/0*qKGxfAPQX4ZYrlZL.png)</center>\n## Proof of Stake (POS)\n\nComparatively to proof of work algorithm where blocks are created by miners and their computational power at hand, proof of stake ensures blocks are added to the blockchain by minters who stake their tokens for proposing the next block. The weight of each validator depends on the number of tokens (stake) available in their wallet.\n\nUnlike to POW used in Bitcoin, Proof of stake consensus mechanism does not use anny miners or heavy computation power to valdate blocks. Instead, their stake is used in order to validate the next block in exchange of a reward. If they commit fraud, their stake would fall in value, which in theory eliminates fraud. \nProof of stake has a few advantages over Proof of Work as follows:\n- *Efficiency* - since it does not require intense computational power to add new blocks, it is more environmental friendly.\n- *Cheaper* - It does not require expensive equipment to run and consumes less energy.\n- *Less centralized* - there is no advantage over collusion. However, it favours large stake holders.\n- *Secure* - neutralizes the 51% attacks as a holder would need to buy a lot of coins to do so.\n\nArguably, POS seems less centralized than POW but that is not necesarelly true. Since investors receive interest on their long positions, proof of stake encourages hoarding more than proof of work. As Andreas Antonopoulos explained during the *Wisma BeeOn Group in Kuala Lumpur, Malaysia*, **proof of stake allows the rich to get richer therefore having a centralizing impact on the holders of the cryptocurrency**. In contrast, proof of work miners are forced to release a certain number of coins to the market in order to invest in new mining hardware and to pay electricity bills which allows a relatively constant amount of newly mined Bitcoins to hit the market every day.\n<center>![proof-of-work](https://cdn-images-1.medium.com/max/1000/0*qKGxfAPQX4ZYrlZL.png)</center>\n## Conclusion\n<center>![proof-of-work](https://file.globalupload.io/4DrfN9DU7v.jpg)</center>\n\nWhen it comes to adopting new protocols in Blockchain technology there is always a trade-off between Security, Scalability and Decentralization. This is often known as ***The Blockchain Trilema***. The more centralized the decision-making process is, the faster the decision can be taken and the more scalable the network is. On the other hand, the less centralized a network is, the longer it takes to come to a consensus.\n\nFinding the perfect balance between the three is going to be a challenging quest in the following years and, as we speak, brilliant minds are working to different consensus mechanisms that could potentially achieve the balance. As of such there is Delegated Proof of stake, Byzantine fault tolerance or Direct Acyclic graph. While I am  optimistic about the ability of active developers to overcome the scaling problem in the long run, I must recognize that proof of work’s proven track record of at least ten years makes it the undefeated champion of consensus mechanisms; at least for now. \n\n<center>![proof-of-work](https://cdn-images-1.medium.com/max/1000/0*qKGxfAPQX4ZYrlZL.png)</center>\n\nI hope you enjoyed this post and found it useful.

I'm sure most of you know about it, but for those who don't, IPFS is a peer-to-peer hypermedia protocol aimed to replace the good old HTTP and make web faster, safer and more open. It is decentralised, uses a similar peer-to-peer protocol to BitTorrent and versioning system to Git. (I will not cover the inner workings of IPFS here, maybe I`ll do that in another post). \nHowever, after finishing my dissertation I wanted to explore IPFS further and built myself a static porfolio website, uploaded on IPFS and voila! Free decentralized hosting.\n\nYou can check out my IPFS hosted website [here][1]\n\n\nNow, I know what you think: \n--*What sort of sorcery is this?*--\nFear not, below I will go with you through the steps you need in order to host your website on IPFS.\n\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n#### Step 1: Install IPFS\n\nDownload IPFS for your platform, and install it as instructed on [official IPFS docs][2]\nI use Ubuntu Linux, so after downloading, I will unzip it and install using the following commands:\n\n```sh\n$ tar xvfz go-ipfs.tar.gz\n$ cd go-ipfs\n$ ./install.sh\n```\n\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n#### Step 2: Prepare your files\n\nI will asume that you have at available the files you want to upload on IPFS. \nDon't worry if you don't have them. Below is a quick `html` annd `css` examples that you can use, which I copied from w3schools.com. Nothing fancy.\n##### index.html\n```language-html\n<!DOCTYPE html>\n<link rel=\"stylesheet\" type=\"text/css\" href=\"styles.css\">\n<html>\n    <body>\n        <h1>My First Heading</h1>\n        <p>My first paragraph.</p>\n    </body>\n</html>\n```\n##### styles.css\n```language-css\nbody {\n    background-color: #ccc;\n}\n```\n\nSave these as `index.html` file and `style.css`\n\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n#### Step 3: Start IPFS\nYou can easily start your IPFS node with the command:\n\n```sh\n$ ipfs daemon\n```\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n#### Step 4: Upload to IPFS\nMy files are stored on the desktop in a folder called `test-ipfs`. \nRunning the following command from your terminal will add the whole folder to the IPFS and generate an address for each of your files:\n\n```sh\n$ ipfs add -r test-ipfs/\n```\n##### Output:\n```sh\nadded QmX6Q9HfSNwDZuXvQRMNewmPUGp8uS5Ef6dPbF2AYw792M test-ipfs/index.html\nadded QmXBuwyFQvGy5Zq5MUW5FxcFfxw1YFnbsPuHLYpZUZ82Rd test-ipfs/styles.css\nadded QmaEBknbGT4bTQiQoe2VNgBJbRfygQGktnaW5TbuKixjYL test-ipfs\n```\nThe hash generated on the last line is the root of your site. You can access it by opening:\n`https://gateway.ipfs.io/ipfs/<your hash here>`. So the example site can be found here:\n[`https://gateway.ipfs.io/ipfs/QmaEBknbGT4bTQiQoe2VNgBJbRfygQGktnaW5TbuKixjYL`][3]\n\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n#### Step 5: Access your website through a gateway\nIPFS will host your website as long as it is accessed by other peers as it propagates to other nodes when it is accessed. Considering this, there are a few ways to make sure your website is accessible anytime as follows:\n\n- Run your own node and host it there (and contribute to IPFS network).\n- Use an IPFS gateway to host your website.\n\nPersonally I have used the latter and chosed Infura.io to permanently host my website. You can simply do the same by accessing the hash generated for your content through their gateway as follows:\n[`https://ipfs.infura.io/ipfs/QmaEBknbGT4bTQiQoe2VNgBJbRfygQGktnaW5TbuKixjYL/`][3]\nNotice that we only changed `gateway.ipfs.io` to `ipfs.infura.io` in our link.\nThis will access the content requested through the infura node and by doing so will permanently create a copy of the files.\n\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n### Future implementations\n\nHosting your content on IPFS using infura is great to start with. However, there are a couple of issues with the whole IPFS approach:\n- Website address is ugly and no one will ever remember it. We need a way to make it prettier like something.com or anything.org.\n- Anytime you make a change to your website and upload it again on IPFS the hash of your content will change, meaning the address of the website will change too.\n\nCurrenlty, there is no easy fix for these issues. It is important to remember that IPFS technology is in it's early days and there is room for it to grow.\nThese issues are explored by different means of trying to solve them in this [article][5] on Hackernoon by Mark Pors.\n\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\nI hope you enjoyed this post and found it useful, and please, if you found a fix to any of the problems above, post it in the comments below!\n#### [Follow me][6]\n\n---\n###### media by [mr.div][7]\n\n\n[1]: https://ipfs.infura.io/ipfs/QmUbw27P1w1Q8Rejr9YB4aKCkHnDq1CxyVhsXvywoudoSq/\n[2]: https://ipfs.io/docs/install/\n[3]: https://gateway.ipfs.io/ipfs/QmaEBknbGT4bTQiQoe2VNgBJbRfygQGktnaW5TbuKixjYL\n[4]: https://ipfs.io/\n[5]: https://hackernoon.com/ten-terrible-attempts-to-make-the-inter-planetary-file-system-human-friendly-e4e95df0c6fa\n[6]: https://steemit.com/@cryptoctave\n[7]: http://mrdiv.tumblr.com",

This time I have decided to focus on answering the question of airdrops. The reason I am doing this is because, lately I got involved in a random airdrop of 1000 CNX tokens that landed in my wallet. I have managed to trade the CNX tokens for a very good deal which got me into exploring this concept further. \nI will cover what airdrops are and why they exist in the first place, also how they work and how to stay on the safe side without compromising your <a href=\"https://steemit.com/cryptocurrency/@cryptoctave/crypto-wallets-or-how-to-keep-my-funds-secure\">wallet security</a>.\n\t\n---\n\n## What are airdrops?\n\nIn a non-crypto context, airdrops are used to deliver food and supplies in boxes to people that cannot be reached in other ways. They are normally dropped from airplanes with parachutes attached  so that they reach people on the ground safely.\n\nIn the crypto context, airdrops are used to distribute crypto assets, such as coins and tokens, to as many people as possible. These assets can become valuable and therefore many people are becoming  interested in receiving these airdrops and trading them . It might sound like a crazy idea, that people are getting valuable coins for free. As crazy as it sounds it's  true. Partially.\n\nThere is an old proverb saying that \n>*\"If you and not paying for the product, you are the product itself\"*\n\nWhat this normally means is that you end up giving your contact details or more to the people distributing  the airdrops. That might be something that you are or not comfortable with.\n\nHowever, not all projects are legitimate and crypto space is still a digital wild wild west. This means you should protect yourself and use different email addresses and passwords for crypto related accounts you set up. If available, you should also secure your accounts with 2-factor authentication. And lastly, keep your private keys safely and never share them with anyone. `If anyone asks you for your PK, never trust them`.\n\t \n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n\n## Who distributes them?\n\nWhen the whitepaper for a ICO project comes out, their token distribution usually  includes a percentage of the tokens that go to the community as rewards. Some of these  rewards will be distributed in an airdrop during, or right after the ICO has finished.\n\nIn the crypto space, whoever distributes an airdrop gets to decide who can take part in the airdrop. Earlier distributions were based on who already had some crypto assets, such as ETH of BTC, in their wallet.\n\nHowever, there are other methods used for airdrops, where the user is requested to provide contact details such as email addresses, Bitcoin talk profile details, Twitter handles, Telegram usernames and so on.\n\nTo  maximize the number of airdrops you can participate in, you should also set up social media accounts, remembering the security tips above. The most common method now is to reward airdrop applicants by using their telegram account to validate the application through a unique referral code they are given. This method can easily be exploited by using multiple sessions with different wallets and referral codes. \n*If you want me to cover this in another post, let me know in the comments below.*\n\nAirdrop applicants can also earn reward by retweeting posts with the relevant hashtags or making posts on facebook. This means that participants earn the airdrop by performing promotional work. This is great, especially if you take part in an airdrop for a project that you support and want to succeed, as it provides you a reward for promoting something you like.\n\t\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n\n## Where to store them?\n\n\t\nIn order to benefit from  the tokens distributed during  airdrops, you will need an ERC20 address to receive the tokens. I personally use <a href=\"https://www.myetherwallet.com/\">MEW (myetherwallet)</a> which I access through my Ledger nano cold-storage.\n\nThe tokens are available to use as soon as you have them in your wallet but sometimes you will find it takes a while until they get adopted by exchanges in order to be traded.\n\nIt is also possible to hold as many wallet addressed you want and benefit from one airdrop many times.\n\nSome airdrops use a proprietary approach and have their own web wallets. Normally such projects intend to build dedicated wallets which can be accessed offline too. Before that they simply store the tokens on their website so you can see your balance as you log into your account.\n\nAnother place where you might get an airdrop are exchanges. This however can be  slightly different as they only happen during a fork. I do not recommend you use any exchange wallet address for ICO airdrops.\n\t\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n\n## What to do with the airdrops?\n\nAfter you received the well deserved tokens, you might wonder what to do with them. Should you hold onto them for the long term or should you sell them immediately. In order to make a healthy decision, you should do your own research to understand what the long term potential is. If you decide to sell them make sure they are traded on the exchange you intend to use.\n\nUnfortunately there is no easy answer to what to do with your new assets, I am not qualified to give investment advice so you might want to consider getting professional advice for that. \n\t \nI hope you enjoy this article and find it useful. \n\n#### <a href=\"https://steemit.com/@cryptoctave\">Follow me</a>\n\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n###### media by <a href=\"http://mrdiv.tumblr.com/page/2\">mr.div</a>",

Each year the Cryptocurrency bubble pops, causing panic and making weak hand sell their stash. Generally there is a lot of <a href=\"https://steemit.com/cryptocurrency/@cryptoctave/25-most-used-cryptocurrency-lingo\">FUD</a> around it spread by media and it happens right after a spike in the total marketcap valuation. You don't  need to go far to validate my statement; this can be seen by studying charts from previous years on <a href=\"https://coinmarketcap.com/\">Coinmarketcap</a> and relate them to past events and news.\n\n## Bloodbath, it's all red!\n   I have only been part of the blockchain ecosystem for little more than a year now; I have seen this bloodbath happen  a few times already and I am sure it will happen again. So if this is your first time experiencing the  insane volatility , let me share a few tips, that you should keep in mind while  investing in cryptocurrencies. \n   These tips will hold you steady over the long term, helping you to  earn a healthy return on your investment.\n\n---\n\n## 1. Never invest more than you can afford to lose\n\n   This is a basic principle which is very simple to follow, with a bit of discipline. It might sound simple in theory, but a lot of people tend to invest more than they can afford to lose . Some go even further and are willing to take loans from banks in order to invest  because of <a href=\"https://steemit.com/cryptocurrency/@cryptoctave/25-most-used-cryptocurrency-lingo\">FOMO</a>. \n   Remember, as an asset class, cryptocurrencies are well known to be the very risky  due to high\nvolatility; it is not uncommon to see double or triple digit percentage increases in a day, but also decreases. There are three things you should take with you from this:\n\n- Never invest more than you can afford to lose , regardless of what people around you are saying.\n- Never get caught up in the <a href=\"https://steemit.com/cryptocurrency/@cryptoctave/25-most-used-cryptocurrency-lingo\">FOMO</a> and do not make sentimental decisions.\n- We are still in the infancy of  blockchain technology and there is still plenty of time, \n\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n## 2. HODL and Research \n\n   Always hold your position during a bloodbath. However, you shouldn't  hold just any cryptocurrency that you come across. By carefully selecting the most valuable projects with a good long term potential, the chances of having a big loss during a bloodbath are less likely. How do you know you’re not investing in pointless, pump and dump coins?  Crypto space is already a risky environment and if you want to take a step further, and play an even riskier game, nobody will  stop you. \n   I personally do not engage in such activities and that is not what I try to teach. If you want real success, invest in valuable projects which have the potential to impact the status quo. Naturally you will be required to do your own research on projects before investing, just as you do with anything else; Crypto is no different. You always  need to do your own research: \n- Who is in the team? \n- What they are aiming to achieve? \n- What past success they had? \n- Are they capable of delivering  the intended product? \n- Do they have a well crafted whitepaper that explains the inner workings of the product?\n\n`HODL the good projects!`\n\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n## To remember:\n   Do your own research and invest in projects that you believe in. Don't put your money into a cryptocurrency just because everyone else did; and more importantly, never invest more that you can afford to lose. You have your own mind to generate your own thoughts and make informed decisions. Use them with crypto and don't let them go out the window. Now to wrap everything up I will leave you with some final points:\n\n- Don't panic buy\n- Don't panic sell\n\n\tThese two are directly linked to the <a href=\"https://steemit.com/cryptocurrency/@cryptoctave/25-most-used-cryptocurrency-lingo\">FOMO</a> mentality and could lead you losing good amounts; Always act when you are ready and 90% confident to buy or sell. \n\n---\n\n   This covers my tips for you; by following these simple rules you will be more likely to have a healthy return in the long run and hold out better during a bloodbath. Let me know if you find this useful and please feel free to share your experiences in the comment section below. Good luck in your crypto endeavours!\n\n#### <a href=\"https://steemit.com/@cryptoctave\">Follow me</a>\n\n<center>![divider.png](https://steemitimages.com/DQmbnWpNQSUjBXo8T6imBw19KyjM89QxP3vxYZvPAMEhva9/divider.png)</center>\n\n###### media by <a href=\"http://mrdiv.tumblr.com/page/2\">mr.div</a>",
