I think bull run on btc is already done when it dumped to $55k and because of it, the market started the alt coin season wherein the top alts are showing a really great trend and pattern.
Not yet. It even dumped to $42k and there were already thoughts that it has ended but it didn't and came back to $55k and now $57k.
If the market is still bullish, it will not easily dump, it always recovers if it will dump, but when correction comes, we will be in the bear season. Looks like now it's very volatile, bitcoin heading now to $60k and it's crucial if it can break the walls and make a new ATH again. The dominance rate of bitcoin has dropped, its altcoins season already, but bitcoin still has room for an increase at it always have, but the more bitcoin will pump, people will eventually shift to bitcoin again leaving the altcoins to dump.
