1% or 2% makes no diff to me as it's a small fraction of a 25BTC payday.
After halving it would have to be re-evaluated as the earnings will drop to 12.5BTC and unless BTC value goes to $1K+ it will cut bigtime into people's earnings.
But its not like his efforts or cost get lessened. Sure its only 12.5 BTC but you would still get 12.375 out of the 12.5 block. He would be making .0625 at the current percentage and still operating at the same cost and effort..... hell I wouldn't want to be in that position, I could understand if he considered shutting it down at that point.
Thus he will have to re-evaluate the fees/costs of the pool.
unless coins go to 1000 usd plus.
we can dream can't we? you should know that
I don't want to de-rail the thread, but I think everyone expects it to go at least that high before halving and after.
