78 RTX 3080s to mine Bitcoin: Earn 70,000 in a month and get back the investment in 9 months

Currently, graphics cards are in short supply in the market. Despite factors such as supply and production capacity, the main reason why users cannot buy them may be "mining."

The latest graphics cards have excellent mining performance, resulting in a large influx of miners and diverting a large amount of inventory.

Recently, someone built 78 RTX 3080 mining machines and lit them up at the same time. They were gorgeous with the RGB lights.

VCZ roughly calculated the profits of the mine from mining Ethereum: the purchase cost of 78 RTX 3080s was approximately US$93,000, which is a one-time cost based on US$100,000.

The electricity cost in Las Vegas where the miner is located is 8.43 cents per kilowatt-hour, and the monthly electricity bill is about $1,444. Adding the cooling cost, the total electricity bill is $2,166, which can cover the purchase cost of RTX 3080 in about 9.5 months.

Of course, this still has a prerequisite, and there is a certain element of "gambling". Once Bitcoin collapses, all these efforts will be in vain. But at present, if the price of Bitcoin continues to rise, then the profits will also rise.
