For me:

good coins: bitcoin, litecoin, monero

potential good coins: decred, siacoin

bad coins: everything ICO & its platform (ETH), copy & paste coins (with the exception on LTC, yeah bcash is NOT an exception) and everything masternodes (w/o decred).

So most cryptopia coins are just bad coins. It doesn't means that you can't make profit trading them.

The next good coin, for me: starts without premine / has something new to offer / it is build by the community / has true developers
