The BTC Dominance is at it's absolute threshold. At 69% Dominance. I know it's practically a meme at this point, but watch the alt coins...
If Bitcoin goes above 70%, I am uncertain the alt coins will ever recover. However, at this point, it could mark the absolute bottom for them.
This could be the greatest buying opportunity on alt coins, in a lifetime... or, they are going to die. We will find out if Bitcoin Dominance reverses right now. If it goes above 70% on CoinMarketCap, I can't say with any reasonable analysis when the alts will reverse, if ever.
Otherwise, this is the bottom of the altcoin market, right now. Moon time.
