Don’t invest blindy. There are people in this world who would sell a blind person a pair of glasses if they could make money. Those same people play in the cryptocurrency markets and use every opportunity to exploit less-informed investors. They’ll tell you what to buy or claim certain coins will moon, just to increase the prices so they can exit. Due to the highly speculative nature of the cryptocurrency markets today, a good investor will always do his or her own research in order to take full responsibility for the potential investment outcome. Information coming from even the best investor is, at best, great information, but never a promise, so you can still get burned.
TIP: If you don’t understand the tax implications of trading cryptocurrency tread very carefully. There are some nasty traps you could fall into when trading coins. For one, they are not necessarily considered “like-kind assets.” If that is confusing, then consider sticking with trading USD for coins in Coinbase until you grasp the concept. Learn about cryptocurrency and taxes.
We've had splits in the technical community before. Two years ago, Angular was the dominant Javascript framework and React was new with a small following. Angular's community split between Angular 1 and 2. Today, there are 236,472 repo's associated with React compared 247,335 for both angular variants. Alone, interest in react is about to supercede both variants of Angular combined.

The second reason to buy the most liquid coins is that there are risks of scams. When you purchase Bitcoin you are sure that you will be able to sell it to somebody later. However, when you buy X coin, which is not as liquid and as popular as Bitcoin is, your risks are higher as everything depends in this case on the project, its team, goals, roadmap, background etc.
Know thy taxes. Speaking of legal tender like the USD, it is what you use to pay taxes. If you don’t understand Bitcoin’s tax implications, brush up on them before you start power trading. One could get them into a situation where they make money on paper, but end the year down in Bitcoin without taking their loss, and thus end up owing a bunch of money they don’t have in taxes. Those who don’t have investment experience can get in trouble if they don’t understand the somewhat complex implications of trading crypto.

I am not your guru. I’m a crypto enthusiast, not a professional trader, and I make plenty of mistakes. There are a huge amount of ‘gurus’ and ‘experts’ out there but the truth is that many of them haven’t got a fucking clue what they are talking about. Opinions in cryptocurrency are like assholes, everybody’s got one. It’s extremely easy to predict the market and hell, everybody seems like an expert, when cryptocurrency is experiencing a bull run.
The cryptocurrency market is insanely volatile in 2018. You can make a fortune in a moment and lose it in the next whether you trade Bitcoin, another coin, or the GBTC Bitcoin trust. Consider mitigating risks, hedging, and not “going long” with all your investable funds. TIP: If you trade only the top coins by market cap (that is coins like Bitcoin Ethereum), or GBTC, then the chances of losing everything overnight are slim (not impossible, but slim). Other cryptocurrencies are riskier (but can offer quick gains on a good day).

Only invest what you can lose. During the recent crash in January 2018, hobby-investors got burned. Reports of frustration and losses came at the cost of broken monitors, smashed laptops, and heavy monetary losses. While the rules are in more particular order of importance, it’s safe to assume that this is the most important rule, the rule to rule the rules. As soon as your money is converted into cryptocurrency, consider it lost forever. There is absolutely no guarantee you can get it back. Losses don’t simply come from dips in the market; extraordinary factors such as hacks, bugs, and government regulation can mean you’ll never see any of your money again. If you are investing money you can’t afford to lose, you need to take a step back and re-evaluate your current financial situation, because what you’re about to do is an act of desperation. This includes: using credit cards, taking out mortgages, applying for loans, or selling everything and traveling the world (as glamorous as that sounds).
