Bitcoin is supposed to be an apolitical currency, but the United States reportedly gained some leverage by amassing over 27,000 bitcoins — and counting. (People seem to be jumping at the possibility of turning bitcoin into the ultimate unmoderated facebook clone and the "content" there is what you'd expect.)
OTOH, this poses a practical problem for the community, because attempting to redeem this amount would probably destroy the currency's market value.
Now, in the marvellous world of atomic hat-based TF2 trading there is a de-facto authority called SteamRep. In short, what they call a scammer is a scammer. Their items become scammed. Trade for scammed items and you become a scammer. This label shuns you from virtually all trading websites, which will be happy to take for themselves whatever items or currency of yours they hold.
I am not advocating for this. I do not have bitcoins. I don't like bitcoins. I also don't like aiding criminals in their trading and money laundering. That's just my opinion and it's worth its weight in electrons.
I do wonder, though, if it would be technically feasible for the bitcoin community to protect itself from a possible sudden devaluation of the currency by marking a bitcoin wallet, and all the individual fractions of bitcoins in there, as "bad, no, worthless, will not accept, will not process transactions" in an attempt to artificially limit their worth.
