OK. indeed. Sell ​​the Geforce RTX3090 and use that money to rent it with a nice hash.
Thank you for your guidance.

I don't think it's possible, but if the block hits at 2.148Gh / s, isn't it great? It looks interesting, so I'll try mining for a while.

Hashedbet, Sledge0001, thank you for your response. Bitmain S19 is expensive, so I decided to buy GekkoScience Compac FUSB.

I tried mining with stratum + tcp: //solo.ckpool.org: 3333 using OS: Windows11, cgminer ver3.7.2, Geforce RTX 3090. The average speed is displayed as 2.148Gh / s. Is this the correct speed? The GekkoScience Compac F USB is 350Gh / s, but the Geforce RTX 3090 is too slow. Please teach.

My PC is Windows 11. I downloaded cgminer-4.11.0, but cgminer.exe was missing. I think you need a build, but can anyone please tell me how to do it?

Thank you very much. It was a capital letter. It was a too rudimentary cause.

I am a beginner in mining. This time, I borrowed hash power with NiceHash and mined for 12 o'clock, but the hash speed is not reflected in http://solo.ckpool.org/users/. We will post the rental settings of NiceHash, so please tell us about the cause. Thank you.
