When BTC finally hits a high plain and starts to pullback is when the altcoins will run again. Altcoins go down when BTC rises, and then the opposite happens. Altcoin's season may still be a few years away after Bitcoin halving. We need to see how high BTC will go first, but Altcoins season will be huge in my opinion. BTC dominance is already 67%. Same thing happened Dec 2017. BTC hit new ATH and it's dominance went up to 80%, Alt coins tanked. Then when BTC started to correct, Altcoins shot to the moon. Same will happen again.
