Which site is good for renting hash? Is it good and reliable?
Who can recommend a rental service?
I used both miningrentals and nicehash. Now not really using nicehash due to the amount of KYC and even having to verify the wallet you send from. I am concerned it may cause issue so avoiding that hassle.
However, you can concentrate a lot of hash in one go on there as the rent is for actual hash power and not a rig. You set the price your willing to pay and how much speed. If your bid is high enough you can go nuts, if your bid is competitive it may come, give some, and if a new higher big comes in they will shift over to there. Obviously if too low you could be idle for an awful long time!
Miningrentals you rent rigs for set periods, but can swap them around to different mining pools if you so choose. Many you can extend the rental period, the owners usually set the minimum time to maximum you can rent it for.
Take a look over both and understand how they work, roll the way you feel comfortable.
