I don't recommend to sell it at this time. but all decisions are on your hands. all speculation is always at risk
I think bitcoin will be able to go back to normal and slowly increase.
I too think it's gonna slowly increase, but the question is who will keep investing in a crypto that "just" slowly increases? Knowing the risks, that is. If the BTC keeps just slowly increases, I predict people will quickly move to ALTs, and then BTC crashes again.
