So here’s the question: is the future of crypto shaped by Wall Street investors, or by ordinary people in weaker economies who actually use it?
If you understand the reason why bitcoin remained a decentralized digital currency, then you may not have been saying all these, these same countries and set of people you're referring to are not all investors of bitcoin, taking US for instance, while none of the developed countries as you have mentioned has even supported the adoption of bitcoin as a legal tender, so what are we saying, the wall street are only discussing about what they have invested and seen regarding the price movement.
Can you imagine on the number of investors that are individuals holding across the world, we made a number to constitutes more than the whales we have, the future of bitcoin lies on everyone's hand, if it continues the same way it started being trusted and profitable, its adoption, relevance and value will always increases.
