My advice on investing personal funds is not advised, work as advertising bounty in the portfolio should certainly be ETH. EOS. TRX - long. on the other violas selectively and to your taste
EOS. TRX? Why?
It's better to have the top 5 currencies.
EOS, TRX, ETH, NEM, NEO, etc will be some of the longest living infrastructure coins that you can include.
But it would be wise to diversify by technology as well as locality of the token concentration and team.
