Frequently asked questions
What coins can I mine with the BW L21?
The BW L21 (ASIC) can mine 15 proof-of-work coins on BackPoW, including Quai-Scrypt, AUR-Scrypt, Dogecoin, Stohn. Each coin shows its estimated hashrate, daily revenue and solo block-hit probability.
How profitable is the BW L21 for mining?
Profitability of the BW L21 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 BW L21?
Right now the single highest-earning coin for the BW L21 is Quai-Scrypt (QUAI), at about $0.3237/day gross (gross, before electricity). BackPoW re-ranks every mineable coin daily using live network difficulty and prices, so this can change.
Can the BW L21 solo mine?
Yes. BackPoW computes the BW L21'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 BW L21 take to solo mine one Quai-Scrypt block?
About one Quai-Scrypt (QUAI) block every 7.8 h on average at the BW L21's rated hashrate, using Quai-Scrypt's live network hashrate. Real results are random (Poisson) around this mean, recalculated every update.
What is the breakeven electricity rate for the BW L21?
The BW L21 breaks even at approximately 0.0142 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.
