I’ve met so many people that are speculating in crypto these days that have never even read Satoshi’s white paper on Bitcoin. Not only are they not practitioners (tech experts), they even are too lazy or too blinded by greed to even do a baseline level of work. There are many easy ways to quickly get up to speed on crypto and educate oneself you just have to do the work (one of my go-to resources is a company called Oddup which is an ICO/Crypto rating company used by all the major crypto hedge funds and institutional players).
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).
