I think in essence is that it can also depend on its legality in our respective countries, people may be more active or transact crypto in various media. If it's still prohibited, of course only on one side make an effort in investing or trading, and not in everyday life as well as buying particular goods or service.
The other side of using bitcoin is gambling, maybe you know the gambling industry has increased when a bitcoin came. As the signature you are using is part of gambling that uses bitcoin, I guess in the next few years there will be many people who use bitcoin as a gambling system, considering that today there are still many countries that prohibit gambling in their country while online gambling is getting crowded, at least it will make everyone comfortable with the system of anonymity.
