92 billion coins
4.3 minute blocks
.......
Why even bother ?.
GPU mining ??
There's no gpu mining (yet and probably long time) and based on my personal experience we won't see 92 billion coins until about 300 years. Just mine with the wallet as it states in the OP and come back in a week you may have 40-150 coins. This is high coin count with mega slow distribution. In other words no miner dumps and cpu only.
Just do the math. 256 seconds per block * 16 coins/block = ~2M coins a year. Are you really concerned about coins found 46,640 years from now? If not, there are 2M coins available over the next 12 months - go get some.
