How many years will it take to beat the price of video cards with new mining algorithms

Just a day after the "Merge" of Ethereum, during which the cryptocurrency successfully transitioned fromProof of Work (PoW) to Proof of Stake

(PoS), the profitability of GPU mining has "completely collapsed," according to Tom's Hardware.

If you look at WhatToMine and usethe standard US $0.10 per kWh, then the GeForce RTX 3090 and Radeon RX 6800 and 6800 XT show the best results. According to the publication, the profit comes out to about $ 0.06 per day after the cost of electricity. However, the calculations do not take into account other costs and wear of the video card.

Even with a slightly positive net resultit will take more than 20 years to recoup the cost of the RX 6800. However, it is worth considering that no one can predict how the cryptocurrency market will look even in a year, let alone 20 years in the future. This is a volatile market and there are certainly many groups and individuals hoping to find a way to make GPU mining profitable again.

Of the 21 current-generation graphics cards — AMD's RX 6000 series and Nvidia's RTX 30 series — only five are theoretically profitable right now, and they're almost in the red, reportsedition.
