I don't think the government will explicitly ban bitcoin or miners, but they will definitely make it highly taboo to touch it for banks.  Especially if it threatens central banking powers.  They will likely create a false flag scenario where bitcoin was used for drugs, terrorism, child pornography.  They just have banks barred from doing business with crypto exchanges.  It won't be a full press ban, but a stranglehold restriction which will probably be more effective than making it illegal (which I do agree would raise its value as a black market asset).

Recently Brett Sherman was nominated to chair of Investor Protection, Entrepreneurship and Capital Markets. He will surely have the power to influence bills that can get introduced into Congress. He has been incredibly anti-bitcoin and will surely try to pass bills that will stifle the growth of the industry. Also recently BIS head has been advocating Central Banks begin to use digital currencies for themselves. This will surely play out as a way to out-compete crypto.

Discussion: How can they community rally together for what is to come? Are we ready for when governments restrict / sanction any capital flow into exchanges? How prepared are we for these things?
