Unfortunately, the US politicians are largely incompetent in technology and currently have market holdings across a lot of different sources (possibly including Bitcoin). So the question becomes: Will the politicians let it fail, or will there be a bailout/support purely on economical reasons.

We can't look at Bitcoin as a purely economical issue. There are a lot of facets that need to be understood.

DeFi COULD be useful for people in under-developed or generally economically limited countries but I believe that the implementation needs to go back to phase-0 and solve many of the speculative issues that are inherent in DeFi today.
