MicroBT and Bitmain's latest bitcoin mining machines are most profitable now after halving

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.
