why on earth should a solo-miner pay someone any fee, what he can get for free @127.0.0.1 ?
And even, if he got it for 0%, why should a solo-miner risk his reward, if the "solo-pool" is beeing attacked?
I have been mining here for a while - and found a block here after having loads of problems running my own solo mining farm... all i have to do is point my miners here and not worry about having to run a full fat bitcoin node and the the software and the checking. In one fell swoop i had over 100% ROI and electricity costs covered for a couple of years.
