Frequently asked questions
What coins can I mine with the 21energy Ofen 3 Base?
The 21energy Ofen 3 Base (ASIC) can mine 9 proof-of-work coins on BackPoW, including BitcoinCash, Quai-SHA, Bitcoin, Fractal. Each coin shows its estimated hashrate, daily revenue and solo block-hit probability.
How profitable is the 21energy Ofen 3 Base for mining?
Profitability of the 21energy Ofen 3 Base depends on the coin, its network difficulty, the coin price, your electricity cost and pool fees. BackPoW ranks every mineable coin by daily, monthly and annual profit so you can pick the best target.
What is the best coin to mine with the 21energy Ofen 3 Base?
Right now the single highest-earning coin for the 21energy Ofen 3 Base is BitcoinCash (BCH), at about $1.58/day gross (gross, before electricity). BackPoW re-ranks every mineable coin daily using live network difficulty and prices, so this can change.
Can the 21energy Ofen 3 Base solo mine?
Yes. BackPoW computes the 21energy Ofen 3 Base's solo block-hit probability per coin using a Poisson model based on live network hashrate, so you can gauge your realistic chance of finding a block.
How long would the 21energy Ofen 3 Base take to solo mine one BitcoinCash block?
About one BitcoinCash (BCH) block every 1.6 years on average at the 21energy Ofen 3 Base's rated hashrate, using BitcoinCash's live network hashrate. Real results are random (Poisson) around this mean, recalculated every update.
Where can I solo mine with the 21energy Ofen 3 Base?
You can solo mine BitcoinCash with the 21energy Ofen 3 Base by connecting to verified solo stratum gateways such as harshy.site, fastpool.xyz, luckymonster.pro. These pools forward 100% of the block reward directly to your wallet upon discovery (minus standard pool fees).
What is the breakeven electricity rate for the 21energy Ofen 3 Base?
The 21energy Ofen 3 Base breaks even at approximately 0.0657 USD/kWh. If your electricity tariff is below this threshold, mining is profitable at current coin prices and network difficulty. Above this rate, power costs exceed daily revenue and the miner operates at a loss. BackPoW recalculates this figure every update.
