Leading Chinese manufacturers of ASIC miners MicroBT, Canaan and Ebang have sold through their inventories this year, while Bitmain is grappling with supply disruptions due to a founders’ rift. As a result, bitcoin miners are confronting a shortage of supply for new devices, according to 8btc, citing its own sources.
ForkLog sources within the mining community said that the information about the shortage may not reflect reality.
“MicroBT is shipping normally, and for Canaan all units have been snapped up by resellers. There is market supply, inventories are full both in Russia and in China,” our source emphasised.
8btc noted that MicroBT, Canaan, Ebang and Innosilicon are using Samsung’s 8-nanometre ASIC chip. The Korean corporation is facing problems with OEM orders for Qualcomm’s manufacturing capacity.
Bitmain uses a 7-nanometre chip manufactured by TSMC, but due to disagreements between co-founders Jihan Wu and Micree Zhan, neither side fully controls the supply chain for mining hardware.
Innosilicon claims it will release in the second half of 2020 a new generation of ASIC miners with an energy efficiency of 20 W/TH. MicroBT is also concentrating on the release of the next product line, according to 8btc.
Earlier, Micree Zhang announced the launch of miners built on 5-nm chips, with shipments starting in January 2021.
Canaan in June unveiled new bitcoin mining devices, significantly lagging in efficiency compared with previously released flagships from MicroBT and Bitmain. Shipments of the AvalonMiner 1166 Pro are also planned for January next year.
According to the Chinese edition, the majority of MicroBT’s produced Whatsminer M30S miners were sold abroad, with Bitmain also securing a sizable share of foreign orders.
Earlier, the leading bitcoin-miner manufacturer signed large supply contracts for Antminer S19 Pro with American companies: for $28.8 million with Riot Blockchain and for $23 million with Marathon Patent Group.
