I normally stick to what I am able to purchase on Bittrex, that I way I don't have to worry about sketchy exchanges, and aren't really going for ICOs(besides a couple of the really big ones like LAT), but rather buying coins directly at exchange. I have generally found it rather easy to obtain any of the below mentioned coins at Bittrex.
I currently have some of each of the following coins:
Musicoin
Ripple
BURST
Verge
Siacoin
WhiteCoin
ReddCoin
Status Network Token
SafeExchangeCoin
LAT
NVOS
Eth
Monero
