i Was going through 2021 Bull market and found that Altcoins Dropped 50-60% on average in 2021 bull market and it goes for new highs again.
Take a look at the pictures i attached.
$ETH dropped 60% despite being the second biggest crypto.
$SOL did almost 50% and $DOT faced 78% dump.
We are in a similar situation right now I don't know if we will see new highs on every Altcoin. Not every coin will make it that far but i do know we are still in a bull market as long as Bitcoin is holding fine and I don't see any changes on BTC.
