I advise you to buy altcoins that have been proven and real progress, which they certainly have teams that are constantly trying to develop their altcoins.
I think NEO and ETH are the best altcoins currently.
i am agree with you.today we see in market bitcoin dominance reach more than 55% , and most altcoin are cheap right now.best time to buy and wait till bitcoin dominance back to around 30% . i am sure it will soar sharply.
