Frequently asked
About the 21energy Bitcoin Heater 3500
Can the 21energy Bitcoin Heater 3500 sell hashrate on NiceHash?
Yes. NiceHash and similar hashrate marketplaces (Mining Rig Rentals, etc.) let the 21energy Bitcoin Heater 3500 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.
NiceHash or Mining Rig Rentals — which is better for the 21energy Bitcoin Heater 3500?
NiceHash settles instantly at a market-weighted price. Mining Rig Rentals shows three levels: floor (cheapest seller), recent (last 10 actual rentals), and asking (aspirational seller wishlist). Prefer NiceHash for fire-and-forget income; prefer MRR if you want to set your own price and accept lower utilization.
Should the 21energy Bitcoin Heater 3500 sell Sha256 hashrate or mine direct?
Selling hashrate on NiceHash pays in BTC at the marketplace's clearing rate, so you avoid coin-price risk on the underlying Sha256 coin. Direct mining pays in the native coin at the live block reward, so you keep upside if Sha256 appreciates. Compare daily $ income side by side in the table above.
