You're not gonna make more - just they're gonna get money from you via fees or hacks in the miner.
Of course they also don't provide source code ... so you don't see the hacks that steal from you
... and they of course are breaking the license terms for not providing the source code.
If you do use it - mine somewhere else with it - I don't want to be dealing with people complaining about lost shares and problems here due to hacked miners
... or the pool losing blocks due to the hacks.
but if you have more equal miners, and you flash some of them, it should be fairly easy to compare and see if that would be true?
Also, with the improved mining algo, it should benefit a higher hasrate...
In other words: if a 13.5Th miner would go to 16-17Th and use less power, why would i care they take one or 2 percent of my mining hashrate? (all things being equal..)
You really think Bitmain wouldn't advertise and sell their miners saying they do 16-17THs if they could do that?
... and again - regarding blocks:
So they've tested and proven that their modified code consistently finds real blocks on the Bitcoin network?
