No one can predict whats happens next. Likewise dont know what will going to happen in the coinmarketcap. But i assume some coins in the coinmarketcap that will have good future. Coins such as

Ethereum
Ripple
Litecoin
Neo
Cardano
TRON
IOTA
Bitcoincash.

These are coins have good support and shows their healthy growth in recent days. So invest in these coins will be more useful in future.
