If you know anyone who can do without some non-zero amount of cash today, with the expectation of a 50% gain by 8 Feb, you should inform them, or you are no friend.
Ha, I understand what you're saying, but these things are mere conjectures. They're no facts, yet. Bitcoin remains a high-risk investment vehicle.

I'd really like to know some educates guesses on when COIN really launches!
