Mining this coin: FAQ
Is Iron Fish mining profitable right now?
Iron Fish is mined on GPUs (FishHash). We track ASIC miners only, so we don't rank machines for it; one MH earns about $0.00846 a day before power and pool fees at today's price.
How much does Iron Fish mining earn per MH?
About $0.00846 per MH per day before electricity and pool fees, at today's price of $0.0747 and network hashrate of 215 GH/s. It moves with both.
How do Iron Fish's block rewards and supply work?
Right now each block pays about 17.3 IRON including fees, with a block every 61 seconds on average, about 24,433 IRON a day. About 66.65 million IRON exist today and there is no hard cap.
What hardware mines FishHash, and what matters when buying?
FishHash is built to keep mining on graphics cards: it is memory-hard and changes its work so that fixed-function chips gain little. There are no mainstream ASICs for it, so GPU rigs (and sometimes CPUs) do the work, and profit depends on your cards, their power limits and your electricity price.
How do I start mining Iron Fish?
You need GPUs that suit FishHash (memory size matters for most GPU algorithms), mining software that supports it, an Iron Fish wallet and a pool. Profit depends almost entirely on your electricity price, so check it against the earnings per MH above before buying cards.
