I don’t think they’ll be successful, they can try though
Well they do recognize the legitimacy of cryptocurrency, only to tax it into the ground, or regulate it and curtail its growth. Do you believe the greedy politicians in the US appreciate an alternate currency that competes with USD? Or do you believe they recognize BTC for its merits as an asset, only with intent to generate income from it? A USD competitor is bad for the US no matter how many "pro-crypto" politicians there are. If you're a US politician, there is no supporting both.
