Most probably yes because at this moment bitcoin is just starting hes popularity around the world. Im not saying that the 20k will achieve before the end or after of this year but i am realy sure that bitcoin will go back to that price again and even higher than that 20k price.
There is a possibility indeed that bitcoin price may reach 20k as the price lately is slowly recovering. The most answer to this is we do not know when bitcoin can make it back to that value. On my view, I think not this year probably the following year. Once more adoption and more demands the possibility is high to reach to 20k.
