no, I don't believe bitcoin can fall to the price of $ 1500, the worst fall in the price of bitcoin will only reach $ 4k-$ 5k because the demand for bitcoin is very high and lots of buying orders at $ 5k are bitcoin's difficulty falling deeper.
Yes, I believe so that the price of bitcoin would not fall that deep because there is a lot of demand in which when there is a downfall, especially if it's a sudden movement then we can see an immediate reaction of the demand and then the price would recover and then slowly consolidate.
Unless there would be an event that would convince people to sell their coins at a loss then it may reach that level but for now, it is less likely to happen given the good news that is surrounding the crypto world nowadays.
