Sorry for my Engrish!
Since even Krugman sensei says "Bubble, Bubble, Fraud and Trouble", I want to sell Bitcoin.

I know nothing about FX trading, but if I buy BTC for 10000 yen now, when the price just crash and drop One per million, I will earn Ten billion, right?
I want no risk. Could you recommend companies who allow to sell BTC without leverage?
