Yes, there is a huge possibility the price of Bitcoin can easily reach to more than $20k but in the current situation it is impossible to guess how long it is going to take but there is a huge prediction about the market in the month of the November and December.
I do believe it can hit $20k. I KNOW it will hit $20k, the problem is not "if bitcoin can hit $20k or not", it is more like "when will bitcoin hit $20k".
If its going to stay like this for a long time and reach $5k or even lower and than go to $20k levels in 2020 than that is horrible and that is not being optimistic, why would I invest my income to something that will grow that slowly or stay same for a long period of time just because it will reach high numbers in 2020, I will invest a year later so I won't have to wait that long if that is the case.
People know bitcoin will reach $20k, we just want it to be sooner rather than later.
