Boom 100x increase
I'm not holding my breath for any country to do any sort of official or quasi-official embrace, but geo-politically speaking...
If Russia made a credible statement of support for Bitcoin and support of those who wish to host critical infrastructure I personally would have significantly more confidence that the solution is sound against certain kinds of attacks. If other's felt this way I could see it having a significant impact on the value, but it probably would not be a 100x event in and of itself.
Russia and China both are powerful enough to be autonomous. The West probably has the means of putting sufficient pressure on China to have them crack down on Bitconi infrastructure support if it were of critical importance, and of course they have a lot of hashing power. The same could probably not be said of Russia since we've already used most of our financial ammo in the recent sanctions bullshit and they have their own energy needs covered. The Russians also might be interested in a little payback for these insults if the opportunity arose. What the West could probably not do would be to keep the Chinese hashing gear from being put into box-cars and pop up in Russia a few days later.
I've long argued that Bitcoin is a threat to pretty much any country and that there is a strong possibility that it could be attacked by all more-or-less simultaneously and in a coordinated manner. It occurs to me, however, that a country like Russia or China could clamp down on use of distributed crypto-currencies by their populace yet allow infrastructure support anyway if it were of strategic significance. Or at the very least turn a blind eye to operators who keep the system hobbling along, and especially if there were enough kickbacks going on. China actually seems to do this already to some extent.
Russia could support Bitcoin, but not now, since their ruble is plummeting.
So even if they would support it otherwise, now they wont because its a direct threat to their currency.
USA would not support it normally, but now they do since they are overconfident in their dollars.
Its an upside world
