Is there a marketplace for buying and selling hashrate other than NiceHash? I'm looking for one that completes all three:

• It is no-KYC.
• I can buy hashrate and point it to a ckpool address.
• I can pay them with cryptocurrency.

I have found miningrigrentals(.)com, but I'm not sure if it is legit. It exists since 2014, so I suppose it is legit.
