I think the normal BTC effect will happen. If BTC goes up then Alt coins go down (vice versa).
The normal effect in the past:BTC goes up, alts go down; BTC stops going up or goes down, alts halt or go down.
The normal effect today:BTC goes up, alts slightly go down waiting for BTC to stop going up to jump much higher than they were at the beginning of the cycle. Rinse and repeat.
I talk about some of the top 10-20 alts.
