I do completely agree with TheAnalogKid:
Rentals are just another way to make normalized income, a steady stream which may be lower, but suffers from less variance.
Whenever i want to rent some hash, I'm sure the the hashes aren't going anywhere but to our pointed pool, as a renter I will constantly check the hashrate i rented....as long as the hashes speed is running accordingly, that's it, no problem at all.
Cheers.
I'm more amused by using the word "suffer" - always good to throw in a word to make people think it's terrible.
One could also say "they have less variance" - means the same thing but without a hidden agenda to mislead people.
Helps sway the minds of those who have no idea what they are doing ...
The only "suffering" I see is renters and to a smaller extent miners.
The proxy happily takes a % no matter what happens.
They don't care to manage history of the miners to ensure the people who are paying their income don't get ripped of - all they care about is their %.
