After 20 years, this is quite possible. If bitcoin continues its rapid development, we can soon see such an increase in value Grow 250x . Cryptocurrency is the future.
I really don’t see anything for now that is stopping the rapid growth of bitcoin, bitcoin has attracted the attention of a lot of people that I would not even believe that could be a partner in this, those bigger institutions that we will soon be seeing their effect on the market will enforce its adoption on other institutions too.
So, 20 years is really a long time that is more than enough for bitcoin to really develop to its fullest and become useful for store value like Gold. Majority of people will tend to hold it then as digital store value which will make it become stable for everyone to rely more on it.
