stop the rubbish, Willy was only active on Gox. And because LITTLE TO NO FIAT WAS LEAVING GOX, arbitrage was not possible and the price rise on all other exchanges, was driven by REAL EXISTING fiat.
sure, Gox prices were leading the way and indirectly drove up prices by motivating people to trade at higher prices everywhere else.
HOWEVER, the fiat used for these purchases was real, it came from real people, and still exists today, in exchanges and bank accounts. Prices can therefore go back to 1200 with this exact same liquidity.
It is a blatant lie and a myth if people say, BTC would be at $100 without the virtual Willy money
