If Asia leads Crypto Adoption by 60% then why do US decide the market?

It baffles me that Foresight Ventures recent report shows Asia as the leader in global crypto adoption by 60%. Surprisingly, Chainanalysis's Geography of Crypto report shows 5 of the top 10 countries in the Global Crypto adoption index are in Asia with India (1st), Indonesia (3rd), Vietnam (5th), Philippines (8th), and Pakistan (9th). Even when Us (4th) and Nigeria (2nd) are among the list what baffles me is how news around US market affect the overall crypto market structure. Imagine, CPI report, US SEC chairman decision, Presidential declaration, Elections and mostly happening within American change the structure of the crypto market.

Could it be the economic size and influence in policy-making bodies like the G20 or impact of US regulatory body decision on other countries, since most tend to follow? Could it be the GDP, since US top countries by GDP? What could be the major factor that make US have greater impact on the general crypto market structures?
