QuoteChina had accounted for about 65% of bitcoins earned through mining, according to the Cambridge Bitcoin Electricity Consumption Index. But analysts think about 90% of its mining has now ceased. Chinese miners are selling their computers at half their value.

Mr Su, who also runs a logistics business that transports mining machines, has been chartering Boeing 747s to get used ones out swiftly. Most are going to Russia and Kazakhstan, which together account for about 13% of the world's bitcoin mining. But there are few data centres abroad with space for lots of new machines, including in America, the second-biggest miner. Building a farm there costs between five and ten times what it does in China, says Mr Su. That is too much for most Chinese miners. More than half of their computers will stay put for now, he says.

With new series cards around the corner from both mfgs, I'd wait about 3-4 months at least.
