Quote from Stok:
SO there are 21 Million coins outstanding or issued?

Quote from Pekelo:
There are currently 11 million mined, and by 2100 something there will be 21 million, I think I will die before that.
Now 1 coin can be divided down to 8 digits, that is 10 000 000 pieces. So the the number of units currently available is 11 followed by 14 zeros...
Some of that 11 million coins have been lost, so it is hard to say how many could be traded, theoretically, all of them....
