Well, with no reason to use them instead of regular fiat, and real risk of government intervention making them worthless, and a continuing supply coming on the market daily, I would guess under 10 cents.  That worth comes from the very small chance this will take off.  A low probability, huge payoff bet.     

Imho of course, and I could be dead wrong.  So diversify.  I personally would start watching charts for a buy point under 1.00, just to see if it sets up.  I might buy some around 10 cents regardless of charts.
