Bitcoin (BTC) is King/Queen; Don’t Get Overly Optimistic About Altcoins. Those who invest in BTC tend to get itchy fingers when BTC stagnates and alts go up. Sure, going into IOTA or ZCash can be a brilliant move at times… at other times you’ll be holding the bag while everyone moves back into BTC. Stick with coins you know and like, but consider always being partly in BTC (not 24/7, but in general). This advise applies somewhat to Ethereum as well, but first and foremost BTC is the center of the crypto economy.
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).
