BTC
ETH
WAN
MAN
ZRX
Other than that, just flip shit in szn and use Bitmex.
Edit: some other exchange/dex coins too, all of these are better than amost anything else given it's a good ex/dex and token has value
What I don't understand is what criteria you use to arrive at this list, I know for sure any wise investor would add BTC and Ethereum to their portfolio. I don't know why you picked Wanchain and no NEO, Matrix is doing very fine for investors but don't know if it is going to take the leap like NEO did.
