its all about the risk/reward ratio. top 10 are safe, however the gains are x2 - x5 in a year. look in top 100, and you will have more risk, however the gains are larger. beyond the top 100, it is a bet. however if you find the right coin, you can become very rich. i personally like the beyond top 100 coins, because i cannot invest a lot of money, and these can make me wealthy in a few years. top 10 cannot. Deeponion is my bet.
