p.s. OMG just noticed: "Total of 100.000.000.000.000.000 DRK will be mined.". Tell me now, how you suppose this coin to be traded on markets? Do you know that there is no lower prices than 1 satoshi (0.00000001 btc) ? So forget about trading pair DRK/BTC
Traded on markets, you mean, like when? There would be 'only' about 360 million coins in approx. 3 year of existing (haven't made accurate calculations yet), and only god knows when number of coins will reach 100 quadrillion. So trading shouldn't be a real problem in the nearest future.
And I actually see no reason why this coin limit should exist (except to astonish us).
upd: I made a mistake. It actually would be more like 4,5 trillion coins in 3 years. So yes, it would be unacceptable for btc market.
