the thing here is that Bitcoin is like gold, and like gold it has to pass through fire to become what it is today, so Bitcoin is the fire purging the whole crypto space, at the moment i think no other currency in the world can shake the price, remember that alot of people are seeing what Bitcoin could be in the future... at the moment i think Bitcoin could only drop to maximum of 4500$ and head straight to 8000$
I also expect that to happen. Maybe a dip will happen after the fork to shake off the market before another trend will be formed. Consequently , I don't expect that new trend to keep seeing bitcoin diving downwards. This is because users have realised that bitcoin has a great capacity to come back to bullish over time and so many would still hold in there wallet to expect further growth. This will help bitcoin.
That makes sense actually. Bitcoin are the most rehabilitative currency in the world right now. There are altcoins and there is gold and dollars and much other, but the beauty bitcoin have in this regard, couldnt be made possible by any other currency.
So, like you said, people come to know now that bitcoin will come back again dont matter how hard is the dip. It profits.
