If the price increase at $10,000, I don't think it will easily surpass $15,000 because the bitcoin price will increase in the future. But after it reaches $15k, I think the price will make a correction of the price, and maybe the price will get down deeper than before. There are so many possibilities for bitcoin that will happen in the future, and we don't know what will happen later. So we need to wait and see what will happen this year and the next year.
I thinks its a big possibility that it can easily surpass if the price will reach $10k, because we can see it already. But we dont know if what really happen next days for the price of btc, so we patience to wait for the next will happen.
