Just a question - how did you get $10,000,000 worth of bitcoins in the first place?
Please don't tell me you were the guy on the other end of the 10,000 Bitcoin pizza. >.>
And holy cow, good luck on taxes.
I would have to think they bought really early and the Taxes will be non existant consider the whole point is CASH !! What I am doing when the time is right. I would take a lose on %, maybe even 10& to do a cash deal..
