I think it will have an insane amount of difference to make with those countries. For example, they combine make up over 30% of the worlds population, if you put that into perspective if they can bring in billions of dollars with the population that would be insane for bitcoin.

However, you are missing one vital problem, even tho the people there are outnumbering many in other countries they are not as rich as many other European countries and not USA, which means even tho there are a lot of rich people there the number of average joe getting into crypto is a lot harder for them. As Asia will have more than half of world population, we can expect heavy impact into crypto world but that is purely based on their government's states and not definitely by their crypto community.
