I think it reasonable to invest in the top 10-15 alts.
However, I have some doubts about the ETH. What if BNB completely replaces it?
And all the projects and iCO in the future will be on the BNB, and the ETH will gradually die?
well, even BNB have its own chain now,,
but, i still believe with ethereum mate, because ethereum is the best altcoins for me

Ok, only the future can show who is right.
But I am betting on the BNB at the moment.
