Cause using a BTC address on nicehash is hard (or conversely for more flexibility use a proxy you can point wherever). I think you're grossly overestimating the amount of work here to try and make a point. Receiving address splits up end day, week, or whatever you want based on the fee schedule. Very easy to do and program. All it has to do is mine 2 out of 100 shares on Nicehash using the current algorithm that the user has selected.
why would I do that ?
I am sorry, I don't work for nicehash, I am not even a fan of that system and have 0 reason to privilege nicehash over any other pool.
(and actually if I was doing something like, I would clearly expect a retribution from the pool who would have the monopoly over the fastest miner..

yeah I can dream...)
and we all know it would be bad for the coins.
This is the part you really fail to understand over and over again: your own interest isn't the interest of everyone (nor actually mine).
Hence if I make a fee miner, it has to work for all pool, not to force user to move to one pool which is insane.
I think your problem is that you are just greedy and don't give a shit about crypto. (sure I like to make money on it, but I try to not destroy what helps me to make money...)
Because Nicehash is easy and getting it going is the first step to making this work. But as I mentioned you could use a proxy and send it wherever you want and adjust it at the proxy.
This wouldn't be any worse then any other multipool, plus Nicehash can handle spurts of sudden hashing power with ease, is ddos protected, and extremely robust. It's the best solution unless someone can come up with something better.
I'm greedy because I want to pay you guys with my hash... Sorry, once again that doesn't compute, especially from the person selling private miners to select few rich individuals. THAT is exactly what cryptos aren't about. Sharing your hashrate with the developers who make things possible is the complete opposite of that.
i've never had a problem with all my unpowered ribbon cable risers on the 750ti cards. but all my cards have the extra 6 pin power connector though.
Yeah, that six pin helps. I'm guessing this may be different for the 750ti owners who don't have a aux power connector, especially those with higher wattage per card or who have unlocked their bios to provide more volts.
