Can the 21energy Ofen 3 Pro earn from AI rental?
No. The 21energy Ofen 3 Pro is a mining ASIC — it has no general-purpose compute cores and cannot run AI workloads. AI rental is a GPU-only income mode.
What crypto algorithms can the 21energy Ofen 3 Pro mine?

Can the 21energy Ofen 3 Pro sell hashrate on NiceHash?
Yes. NiceHash and similar hashrate marketplaces (Mining Rig Rentals, etc.) let the 21energy Ofen 3 Pro sell its Sha256 hashpower directly — buyers rent the compute, you receive BTC per hash delivered. It is similar to mining, but removes coin-price risk since you are paid in BTC on NiceHash's rate.
