Difficulty increased by a lot.


The target decreased by 31.79%, so you should be generating 31.79% fewer BitCoins.

This is an example of an uneducated miner.  No offense, but I hope you didn't spend too much.  You do know the block reward halves occasionally too right?  Unfortunately I bet there are a lot of people like the OP.

Ah, crap !

This is why mining will become useless within a few years the price for equipment will be too much.

And even then when the market eventually approaches saturation (you'll never keep getting the same efficiency increases) the difficulty will retarget accordingly to maintain the ~ 10 minutes between each block. Hence your difficulty will eventually slow down in its increases and may even fall. There is also always an incentive to mine - even when coin generation stops they will (hopefully) be paid in enough fees to have a reasonably large network.
