It will be very difficult to predict. I have zero doubt that Bitcoin would eventually reach a valuation of a few trillion USD. But at this point, I can't make a reasonable assumption on how much time it is going to take. A lot of factors are involved here and there are a number of risk factors. There can be all sort of combinations and permutations, which makes it impossible to make such a calculation within a reasonable margin of error. Personally for me, it doesn't make any difference whether the new ATH will be achieved in 2021, or in 2025 or by 2030. I am ready to hold even up to 2150. It is an issue for those who doesn't have the necessary patience.
