Shenzhen-based MicroBT is rolling out three new top-of-the-line bitcoin miners amid heated competition with Bitmain ahead of the network’s halving event in less than 30 days.
Chen Jianbing, COO of MicroBT, announced in an online event on Friday that the three new models – the WhatsMiner M30S+, M30S++ and M31S+ – are available via both warehouse inventory and pre-orders that can be delivered in up to 30 days.
The move underscores MicroBT’s neck-and-neck competition in the multi-billion-dollar mining hardware market with major rival Bitmain, which is scheduled to deliver the first batch of its latest AntMiner S19 and S19 Pro miners in May.
At the event, Chen reemphasized MicroBT’s rapid growth in 2019, having achieved sales of 600,000 units of its WhatsMiner M20 series, which, as CoinDesk reported in February, has chipped away at Bitmain’s longstanding market dominance.
The COO said 2019 sales volume had also doubled compared with 2018, boosting its sold computing power to 35 million terahashes per second (TH/s). That accounted for 35 percent of the bitcoin network’s total hash rate as of the end of December.
The new models add to MicroBT’s existing M30 product line, which includes the previously launched WhatsMiner M30S and M31S.
With the latest equipment from both major manufacturers soon to start shipping, the bitcoin mining hardware market is now entering what Chen called the “3X era,” referring to a mining efficiency that’s below 40 watts per terahash (W/T).
For context, W/T measures how much electricity a mining machine consumes for each terahash of computing power. Since bitcoin mining is an energy-intensive computing process, a miner with a lower W/T ratio would be able to bring home a higher gross margin.
This metric has become considerably more important given the upcoming bitcoin halving, which will reduce the amount of bitcoin earned by the mining industry in a day from around 1800 to 900 units.
