The latest models of bitcoin mining machines from Chinese giants MicroBT and Bitmain are the most profitable now after the halving, according to The Block’s research.
MicroBT’s Whatsminer M30S++, which can produce up to 112 terahash per second (TH/s) of hashrate, ranks number one with a daily profit of $8.53.
Bitmain’s Antminer S19 Pro, which can produce up to 110 TH/s hashrate, follows next with a daily profit of $8.49. Notably, Antminer S9, the most popular last-generation miner, is now barely profitable - generating a profit of just $0.52 per day.
As can be seen from the chart above, five out of the ten most profitable machines are MicroBT's Whatsminer models. MicroBT is in a neck-and-neck competition with Bitmain and has rapidly expanded its market share by selling over half a million units in 2019. While Bitmain still dominates, its market share has declined over a period of time.
The profit figures have been calculated assuming the current mining difficulty, bitcoin price of $9,700, and electricity/hosting cost of $0.03 per kilowatt-hour (kWh). It is worth noting that not all miners get cheaper electricity, and thus, profits could vary.
