Maybe we saw BTC surge from 2 - 20k last year becuase of the "dumb money" investors only using Coinbase/ not being aware of the Altcoin market. Does that suggest that BTC gains are "dumb money" and alt coins are "smart(er) money"? In that perspective we'll have to wait for the herd to become comfortable again to start greed buying BTC. For that to happen I think we'll need to see BTC break it's last ATH.
I know people personally who were trying to get into BTC in Nov/December and are all smug now thinking they missed a "Crash", when they see it start to rebound they'll FOMO for sure.
