Looking at the history of the market money always flows into bitcoin, large caps, mid caps, then small and micro caps and it's a series of rising tides. Bitcoin will go up and then go back down as profits flow through the market until bitcoin is perceived to be a "value" again and then spikes back up.

Now is just the pullback from the $3k - $14k or whatever Bitcoin spiked up to. I wouldn't be suprised, however, if we never see some alts hit their previous highs of the 2018 alt market.
