While ck's pool is 24.750 of the 25 coins he also give you the fees earned
So,when you hit that block you get just over or just under 25 coins.
You also get to use his servers to solo mine.
Much cheaper and faster then self solo mining.
I hit 3 blocks on ck's pool he pays fast . Direct to your btc addy your provide.
Ck did I get the fee correct?
Yes. For now it's 1% fee, and since transaction fees are almost always over 1% now, and I always mine full blocks, you're virtually guaranteed of 25BTC or more if you find a block.
