The only remarkable achievement of the Joe Biden administration was the approval of the Spot Bitcoin ETF. But I can mention so many anti-crypto policies that the government enforced. There is no proof that Harris is pro-Bitcoin.
They aren't "pro" or "anti" Bitcoin--they are a normal government doing normal government things. They favor a stable business environment and leave it up to us to drive the success of products like Bitcoin in that environment. They favor putting criminals in prison and keeping consumers safe from fraud. All of this helps drive the price of Bitcoin upward.
