Do we know how much of what Samsung, Apple, Nvidia etc are producing is going into cryptocurency mining?
I found the following article which indicates that some miners are making their own miners, as are some independent hardware stores:
https://www.reuters.com/article/us-crypto-currencies-mining-analysis/computer-shops-embrace-lucrative-business-outfitting-cryptocurrency-miners-idUSKCN1G502LScores of miners from around the world are traveling to places like Hong Kong’s Sham Shui Po and Singapore’s Sim Lim Square to buy the rigs, which the shops’ hardware geeks expertly build behind counters in their cramped boutiques.
Some miners only buy components: a motherboard, graphic processing units, fans, power adapters, a display card and a memory card. But even if the vendors assemble them on the spot for a small fee, the finished product is usually still a relative bargain.
“It’s 30-50 percent cheaper to buy equipment related to cryptomining in Hong Kong than in Europe,” Russian bitcoin miner Dima Popov said. Hong Kong, for instance, has no sales tax and is closer to component suppliers.
Popov buys display cards, motherboards and power supplies in Hong Kong and mines cryptocurrencies in Russia, where electricity is cheaper and the climate is more suitable.
The demand for the rigs has added a new dimension to Asia’s tech shopping hubs whose once bustling business fizzled out in recent years hit by waning demand for personal computers. Storefronts that once catered mostly to locals, selling phones and other consumer gear, are now greeting foreign visitors searching for hardware that might make them rich.
