As the price of Bitcoin continues to break new highs, the prices of mainstream ASIC mining machines are also rising. Taking the Antminer S19 95T as an example, the official website futures price shows 19200 yuan, but the lowest OTC transaction price has reached 25000 yuan. For Bitcoin mining, which has been monopolized by large institutions and giants, mining of Ethereum, the world's second largest cryptocurrency by market value, is much more compatible.
Recently, Simon Byrne, a netizen in Las Vegas, USA, directly used multiple GeForce RTX 3080s to assemble an Ethereum graphics card mining machine. According to the current price/expected price and cost ratio of Ethereum, his family-level Ethereum graphics card Mining profitability is not bad!
According to a foreign media TweakTown report, Simon Byrne's own Ethereum mining machine is composed of 78 Nvidia GeForce RTX 3080 graphics cards. Each row of 6 cards totals 13 rows. Each graphics card consumes about 300W of power. Byrne's self-made mining machine consumes about 23.4KW of power. Of course, this does not include other power consumption (such as heat dissipation and air conditioning, etc. also require power consumption).
As early as 2017, Asustek launched the B250 Mining Expert (B250 Mining Expert), and ASUS H370 in 2018 supports up to 20 graphics cards. However, there are no relevant reports on the market for mining machines that assemble 78 cards at a time like Simon Byrne. The GeForce RTX 3080 launched by Nvidia this year was highly praised by high-end PC gamers. After the product was launched, it was sold out. Due to its excellent performance, many graphics cards were sold to crypto miners. According to a report by the foreign media Bitcoin.com in November, the amount of Nvidia GPUs purchased by Ethereum miners during the quarter was as high as $175 million.
Inka RTX 3080 was launched in September at a price of US$699. However, due to the hot sales and short supply, the current price has risen to US$1,199 (the domestic price is about 10,000 yuan). At current prices, Byrne's installation cost is approximately $93,522.
TweakTown believes that using the Ethash (Phoenix) algorithm, a single GeForce RTX 3080 has a computing power of about 83MH/S. According to the computing power of the entire network at the time of posting, it is estimated that a graphics card can mine about 0.22236870 ETH per month. Therefore, the 78-card miner will mine 17.3 ETH every month! Calculated at the price of this article before the deadline, it is approximately equivalent to 12645 US dollars.
Excluding the (expected) electricity bill, Byrne can earn $10,200 per month from this self-made mining machine, which is nearly $122,400 in one year! The highest price of Ethereum at the best performance in the market was US$1422. If the price of Ethereum rises in the coming year, the profits that this family-assembled mining machine can make will be even higher! In addition, first-level graphics cards like 3080 have a very high residual value. If they are no longer used for mining and resold, they can also achieve good secondary market performance. Therefore, few game enthusiasts sigh, no wonder so many graphics cards have been bought by cryptocurrency miners!
