My opinion is, a ban on mining in the US will make Bitcoin even stronger. Why? Have a look at China banning it last year. The FUD was always like "the majority of hashrate is in China" so China can censor the txs. Now it isn't the case at all = stronger Bitcoin.
The US banning Bitcoin mining would do the same, make the hashrate to spread across the globe even more = stronger Bitcoin.
All the governments around the world (next to impossible) banning Bitcoin mining would completely dismantle all mining companies and the mining machines (ASICs) would go back to millions of users, making Bitcoin decentralised as never before = stronger Bitcoin.
Bitcoin isn't going to lose because of some politicians. They can only push it to make Bitcoin more resilient.
Anyway, I don't think the US is going to push that hard. Not now, not this year. They will just talk and realise they can only damage their own (fiat) economy.
What is incredible to watch is that after a mere decade, Bitcoin grown to a size that even the mighty White House can't ignore it any more. This fact alone, makes me to look forward another decade. It's gonna be epic!
