Re: ★★★ MaruCoin ★★★ NEW X13 ALGO ! ★★★ (CPU) MINE NOW ! [KGW+DGW] ★★★ NO IPO/PM !
Then, if I'm not wrong, with the same difficulty, reward will be higher after block 2000 
No, only if diff > 75, look at the source.. Its a clever strategy
Hmmm, here is what I get :
With diff 25 and block >2000, reward is 138.5 per block.
With diff 25 and block <2000, reward is 3.29 (that's where we are now).
OP says that early miners will profit but I don't see that. It seems that mining this coin now is just wasting time... I will wait for block 2000.
Because DEV didn't expect GPU until block 2000
Be positive, it's not a instamine coin.
