It seems that many 2021 projects got heavily pumped in January, if hey didn't dump from the get go, thus will take the month to cool off I imagine. I don't think this will change the fact that they will pump soon enough as long as good projects etc. At the moment the 2020 coins look the most advertising generally, those from around summer time. The type of defi/polkadot projects that are up 2-3x but otherwise down 50-75% against Bitcoin & Ethereum. Next will be the older coins, those still rekt from 2018 bear markets. Probably up 10x against the dollar, but still down 80-90% against Bitcoin.
Altcoins to me look potentially overvalued against the dollar, but still most are
heavily undervalued against BTC & especially ETH

This is why I believe the altcoin market will pump so hard, many coins are only just beginning their recovery against Bitcoin/Ethereum, even if they've been doing great against the dollar. As unless a coin has gone up 4.5x in past year, it's doing badly. Unless it's more than 6.5x, better off holding Ether.
