BTC Dominance - great altcoin opportunities

Altcoins took recently HUGE hit, some of them dropped more than 70% and despite such a big drop, I think this is just sharp correction in their uptrends.
BTC Dominance clearly set some sort of bottom at 40%, however I think this bottom is just the bottom of WAVE 3, we should be currently in corrective wave 4 and after this wave 4 is finished, BTC dominance should continue below 40% in wave 5.
