When POW will be over?  or never ? Is there end of generating coins ?

I think that there is way too much coins. Distrubution will be problem of that much coins. To make fair distribution, CCB will need more development to increase interest, and also CCB needs time, maybe a few years.
After that CCB will worth, but now is worthless. There is no mining pool, there is no trading exchange, of course can not be sold even at 1 satoshi.
