There are supporters of Bitcoin community in the Congress and Biden can not only ask his party mates in the Congress to kill American Bitcoin mining industry. He will not get enough support to pass such a bill. He will not win no matter how hard he tries to do that and I believe he does not aim at killing American Bitcoin mining industry.
Tax, he and his administration want to get more tax for the nation from American Bitcoin mining industry. He can achieve it but he will not achieve a target to kill this industry, even he wants it.
If Bitcoin miners migrate from the USA. to other nations, the USA. will lose significant tax resource.
Yes and no .....
Why ?
New York (state) banned crypto mining...
`The New York Senate passed Bill S6486D banning cryptocurrency mining in the state when relying on carbon-based energy sources to power their operation.`
If other states follow their lead, which some have, it's game over for most unless your can find another power source that gets round the ban or move to another state that's crypto friendly.
There are states that are also refusing to give out permits / renew them for mining farms as well.
