1.BTC
2.ETH
3.LTC
4.BCH

For me this is the best performing altcoin of cryptocurrencies world market that we accumulate.
Especially the BCH o bitcoin cash.
Because bitcoin cash is proven and a good example of an evolved cryptocurrency that is ready for real world use and is able to cater the needs of retailers such as having faster transactions and lower fees by accepting bitcoin cash instead of fiat for payments.
