Mining cards depreciated sharply after the merger of Ethernet Fang: some miners cleaned Nvidia RTX graphics cards with spray guns, which may enter the market later.

Thanks to CTOnews.com netizens Wu Yanzu and Coje_He for the clue delivery! CTOnews.com September 25 news, on the afternoon of September 15, Etay Fong "merger" The Merge completed, ETH announced the beginning of the 2.0 era, a complete transition from PoW to PoS. As a result, miners who use consumer graphics cards to dig cryptocurrencies will no longer be profitable.

In this case, although a large number of gamers are looking forward to buying cheaper RTX 30 and RX 6000 series graphics cards, the water of mineral cards is indeed very deep, and we do not recommend such graphics cards for users who are not familiar with the field, no matter how nice the seller says.

According to a series of videos posted by @ I_Leak_VN on Twitter, several large mines are ready to sell ore cards, and even a GPU mine in Vietnam seems to have cleaned the cards directly with water before putting them on eBay, then soaked them with ultrasound and plate water to disinfect and remove PCB.

Obviously, this method of flushing directly with a spray gun is very convenient but can easily cause physical damage, and water may enter places where it is difficult to evaporate. In addition, this operation not only removes dirt, but also washes off heat dissipation ointment or silicone grease and, more seriously, damages fans and chips.

In addition, some users reported that the water they washed with spray was not particularly "clean", so it was easy to leave deposits on PCB. After you buy the mine card, once the external graphics card looks clean and tidy, there may be circuit damage, such as short circuit or fire.

CTOnews.com learned that in the past few years, a large number of so-called "mine owners" to buy high-performance graphics cards to dig ETH, resulting in high prices for graphics cards. Now, with the advent of ETH 2.0, the graphics card market is expected to return to its due level soon, even collapsing in the secondary market.
