I just checked 30 days stats and realized, that there're some unexchanged bitcoins from, for example, 2nd of February. It was a long time ago. Does it mean that miners would never get those money?
I don'w know what it is but it's a dust amount of 0.00074039 BTC so it's not really worth anything, especially when split into users. I'll be checking these things manually once I solve more pressing tech issues.
