Has anyone ever herd the proverb "you don't cut down a money tree" ?
Since H20 is making a massive continues profit from middlecoin, and it's been running for quite a long time now, why should he risk stealing?
Even if he does a total smash and grab and stop paying out completely, stealing 100% of mining power, he would only make as much BTC as would have made in a little over a month from a 3% fee. So why should he do that? And if he wants 4% or 5% why not just raise the fee? The average payout is still higher than multipool and hashcows as far as I can tell, even if he doubled the fee.
Before someone does a comparison to another pool over at least a week, and show a continuously higher payout from another pool, everyone should really stop trolling and accusing H2O of stealing.
I have gone my whole life without ever accusing anyone of stealing, and throwing such accusations around so lightly, is really a character flaw that you should work on before it costs you more then a bad forum rating.
