The pattern has been pump on bitcoin followed by pump on altcoins and back again to bitcoin followed again back to the altcoins.
While speaking about this, one analyst explained that he expects BTC to crush altcoins in the coming weeks as it recaptures some of its market dominance.
Willy Woo – a well-respected on-chain analyst – explained in a recent tweet that there are a plethora of factors that all indicate Bitcoin is going to gain against altcoins in the coming few weeks.
“Bull divergence, BTC Dominance, expecting BTC to gain over alts in coming weeks. Waiting for the top indicator to reverse (detects volume movements). ETH currently more bullish than other alts. In that regard, I believe we’re in an era of dual pumpage.”
