As NiceHack is a no-go for me due to KYC, im going to use Mining Rig Rentals again.
I cant seem to get it working to CK pool.
Anyone can share their port/address/diff. if you got it working.
I have successfully used MRR to rent hashrate here with the following config:
Pool Host:Port=solo.ckpool.org:4334
Workername=YourBTCWalletAddress.workername
Password=x [or whatever, it doesn't matter but above I'm using Hi Diff Port 4334 not 3333]
Good luck!
