Well I can think of a few reasons why it has alts havent returned to full glory and those include
1) The full retract isnt over yet and alts are getting started
2) People cashed out of bitcoin and went to bitcoin cash? Because that is up nearly 40% today
3) People cashed out and since the market was 205b and now is 195b the 10b that left probably wasnt alt money to begin with.
these are my best theories and could be way off but I feel like #1 is most probable in this scenario
Excellent answer.
I agree that
1. some people are moving from BTC to BCH
2. some people are totally moving out from the crypto market today
