Bitmain customers are reportedly unhappy with the power output, efficiency, and a potential delay in the delivery of its upcoming mining rigs.
In brief
Bitmain's decision to use 5nm chips in its new machines has reportedly not been received well by Bitcoin miners.
Miners say second-hand options provide better value in terms of power efficiency and output.
Bitmain has already set up an AI subsidiary as an alternative business.
Mining manufacturer Bitmain’s upcoming mining rigs, which plan to use smaller computing chips compared to older models, are facing backlash among miners due to concerns on their efficiency and output, according to news outlet WuBlockchain. A brainchild of Bitmain co-founder Micree Zhan, the rigs use a tiny 5 nanometer-sized computing chip—similar to those used in smartphones—to complete millions of calculations each second for mining Bitcoin. The firm’s current lineup uses relatively larger chips sized 7nm or 12nm. However, the takers for the new machines are scant. The report said that while Zhan is promoting the “world’s first 5nm chip mining machine” to Chinese miners, the latter group is not convinced with the product.

Meanwhile, Jihan Wu, previously the co-founder at Bitmain and currently the CEO of crypto finance firm Matrixport, said Zhan is now close to being bankrupt and is resorting to selling problematic mining machines to withdraw funds, the report noted. Potential buyers confirmed their lack of interest in the 5nm mining rigs. “Bitcoin mining is now ultra-competitive and strategic players have longer time horizons than ever before,” Thomas Heller, the former global business director of Bitcoin mining giant F2Pool, told us.
Heller added that it’s a risky bet to take a huge gamble on the new 5nm machines as other alternatives, and even second-hand options, are still available from ASIC manufacturers or secondary markets.
Whit Gibbs, the CEO of Bitcoin mining and media firm Hashr8, shared the sentiment. He told Decrypt that, “5nm chips would interest miners but I doubt any knowledgeable miners would allocate much capital to this run of chips, given that they're unproven.”
Gibbs added that the years-long power struggle between Wu and Zhan, which ended in 2019 with Wu stepping down from Bitmain, has also affected the company’s production efficiency.
“It's difficult to put much faith in Bitmain considering how the internal turmoil is leading to delayed orders. It is possible that Micree could ship these and find success but I don't believe many miners would be willing to risk their operations on it,” Gibbs said.
Bitcoin mining is a resource extensive industry that is said to use the same amount of electricity as seven nuclear plants each year. Miners pay a lot of upfront costs in electricity, rig maintenance, and labor, creating a sector where fixed costs are immensely high and profits low. As a result, miners are turning to newer methods to attract clients, such as using new chips in their rigs or even pivoting their business towards serving AI firms, which use similar computing setups.
And Bitmain’s already headed in that direction—courtesy of the firm’s Sophon AI subsidiary that launched back in 2018. Because if your Bitcoin mining business fails, the answer is obviously AI.
