Honestly I doubt the price could crash below $45K and whether the bull market is gonna end or not I don't really know for sure but seeing the adoption and institutional investors it's gonna be tougher for bitcoin to go deep down. I expect people would just buy it back at certain price and the correciton is to be expected since bitcoin rally has been going up really high so far.
Don't doubt, expect that it will go down but do not panic about it because this is as they said a correction, price will bounce back up again. The best thing to do is to buy more bitcoin at a lower price because this is an opportunity to buy bitcoin.
But before doing that, make sure to assess the situation first. There are reason why the price is dumping
and knowing what's behind it is important to set your target, buying low and selling high applies whenever
correction happened, you are capable of sorting things out before buying your assets, this is the good time
to pick those cheap coins and hold it, the chance of pumping it back is always possible.
