Catcoin CAT

At 5¢/kWh the most profitable Catcoin miner today, the Lucky Miner LG, earns about $0 a day and burns $0.0144 of electricity, leaving about $0 a day. 0 of 63 Scrypt miners we track are profitable at that price. Set your own power price above and the whole page recalculates.

Ranked by profit per day at 5¢/kWh: Lucky Miner LG ($0/day, 11 MH/s at 12 W), PlebSource Hammer Miner Scrypt ($0/day, 105 MH/s at 25 W), Goldshell DG Card ($0/day, 80 MH/s at 65 W). The most efficient machine we track is the Bitdeer SealMiner DL1 Air at 149.0 J/GH; cheap power favours raw hashrate, expensive power favours efficiency, so the order changes with your price.

At today's price and difficulty the Lucky Miner LG breaks even at about 0¢ per kWh: above that it costs more to run than it earns. The most efficient machine, the Bitdeer SealMiner DL1 Air, keeps paying up to about 3.6¢ per kWh. Pool fees (usually 1-4%), cooling and any hosting margin come on top, so plan with a buffer. Of the 63 machines we track, 5 are in profit at 3¢/kWh, 0 at 6¢ and 0 at 10¢, which is why miners chase cheap power.

On its own, one Lucky Miner LG would find a Catcoin block about once every 2.6 years on average, and luck can stretch that a long way. That is why almost everyone mines in a pool: the pool finds blocks every day and pays each miner by its share of the work. FPPS and PPS+ pools pay a fixed amount per share (fees often 2-4%), PPLNS pools pay out only when the pool finds a block (often 0-2%, but lumpier).

Right now each block pays about 25.0 CAT including fees, with a block every 10 minutes on average, about 3,434 CAT a day. 16.13 million of the 21.00 million maximum are already out (77%).

Scrypt was designed to be memory-hard, but ASICs took over around 2014. Litecoin and Dogecoin share it and are merge-mined (AuxPoW): a Scrypt machine works on both at once and the pool pays out both coins, often with smaller merge-mined coins such as Pepecoin, Dingocoin and Luckycoin on top. Makers include Bitmain (Antminer L series), Elphapex (DG series) and VolcMiner, with Goldshell for small home units. Hashrate is quoted in GH/s. We track 63 Scrypt machines; judge them by J/GH (efficiency) against your power price, then by price per GH, cooling type and the warranty and repair options where you will run them.

Pick a machine for your power price (see the table above), then sort out power and cooling: most ASICs need 200-277 V at 10-30 A each, hydro models usually 380-415 V three-phase and a cooling loop, and air-cooled units are too loud for a home. Set up a Catcoin wallet, point the machine at a pool, and watch temperatures in the first days. If you don't have cheap power and space, hosting is the usual route: a host runs the machine for an all-in price per kWh. CryptoSites.io lists both powered sites and hosting.
