In the past few months, people have lost their enthusiasm for the decline in bitcoin prices.more and more people have already sold their own currency.the bear market has also arrived.
If BTC fall under 5000$, the cryptocurrency market will collapse, but now it can recover back to 10000$ again, may be after WC is finish.
I do not understand why you decided that if bitcoin falls to $ 5000 then the market will collapse. Do you mean completely or just a correction ?
