Yikes!! indeed.

Though I don't know how much OKPay accounts for volume wise, this is again one of those nasty little developments added to the list.

I wouldn't be surprised to see -at a certain point in time, so with the benefit of hindsight, of course...- that this OKPay withdrawal is just another part of the tactical manouevres undertaken by Government institutions to crack down on Bitcoin.  Would the Japanese be next to hit MtGox big time (and thereby trying to hit BTC as they would like to sell you their "lovely deflationary yen" as an alternative   ? )

Yes, I think BTC will survive such Government crackdown, but the only question is: in what shape will it be afterwards?
We'll see.
