So according to what he said, bitcoin price is very high in the 2020-2021 but still, that is only a prediction, and he doesn't know the truth. We can follow or save his prediction so we can see what will happen in that year. But for me, it's better to enjoy the price now and take as much profit as we can so in the future, we will have much money, and we can also sell bitcoin at the high price if his prediction happens.
