You have to research each token, individually, and really get an understanding of it - who created it, who supports it, how it is mined/maintained, and what are people using it for? You have to know which tokens will maintain their demand for future transactions. The top 10 cryptos, maybe top 20, are solid. If you bought some of all of them & waited a couple of years, you'll be a big winner. Some - a minority of them - will fail, have trouble, and/or fall - but most will rise. Once you know what a coin is, what it's used for, and how to trade in and out of it - you're in a great position to be able to make some profits.
