If entrepreneurs are believing that bitcoin will soar high then this won't be impossible to happen. We'll just have to wait and see until December. While the price is low, take the opportunity to have more bitcoin and hold until it gains profit.
This is not about beliefs this is about money it does not get simpler than that, there is not enough money in the market to get that kind of growth, you want bitcoin to grow 10 times its current price in a time span of only 6 months, I cannot say it is impossible since we know that nothing is impossible for bitcoin, but taking into account that we come from a bull market the chances of getting another one the very next year are very low.
