That's very, very bullish. Regulation is bullish on it's own and this type of extremely positive regulation from such an important country is huge.
Saying that, I doubt that caused such a rise but it was very bullish thing that would surely be priced in soon.
The UK saying that aint gonna tax Bitcoin does not result in a parabolic mega/jump in Bitcoins value from $550 topping at $710 within 12 hours and to say otherwise is fkn madness.
The market was stale, without this impetus, it was going back down to to retest lows.
Someone posted in another thread, that Ukraine have limited bank withdrawals...and that is what it is. Capital Flight. People are scared of losing their money and can't get paper cash out of banks so some of them are sending it to Bitstamp. Unless someone within Ukraine puts a stop to transactions to Bitcoin exchanges, there will be more of this to come. That was the first wave of the earliest bank wires since the 28th, which was when the announcement was made.
Certainly wouldn't be shorting Bitcoin right now, no matter how good things look from a TA perspective.
