It's still profitable

Just not when it gets way too low like 0.0..

That is why its more profitable for early adopters. Later down the line there will be less coins per block, halving each 16666 blocks. Value will adjust as this occurs to balance out, if its hard to obtain the coins, the price will rise. It's also about supply and demand.
Hate to bring it to you, but with halving every six days it's not value adjustement, it's just what people call "get rich fast scheme" and the reason why soon enought you will be mining this coin all by yourself.
Halving every 36 days seemed more reasonable, but you discarded it, probably hoping that will give this coin more false value.
