an ideal portfolio should include 10 -30% cash or usdt as many may be trading from time to time in various exchange
We do have our own preferred ideal crypto portfolio and what I can see from OP though this post was from 2017 still he has a good portfolio after all.
But you know what what's missing with OP's portfolio? it is not cash / usdt but it's ethereum. Many are into ethereum but him doesn't have it instead he has chosen waves as his 2nd to the list.
There's few more talks about it here in forum but I also think that's a good portfolio.
