How to Choose a Video Card for Mining
Ethereum is switching to a PoS mining algorithm, which over time will put an end to home mining of ETH. To do this, you will need to stake at least 32 ethers, which at the current exchange rate is tens of millions of rubles, and over time this amount will only increase.
Nonetheless, home mining is alive. It is enough to look at the best graphics cards to find the right device for mining one of the altcoins. A wide range of coins is offered: CFX, RVN and others. Underestimating the significance of this fact can lead to the loss of a great way of earning money.
Criterias of choice
The first step is to check the price of electricity in a particular region, and then make an allowance for a possible increase in the cost of energy. Otherwise, you can buy a card that shows a good hash rate, but consumes so much energy that all income is lost, it goes to pay for electricity.
Hard to believe but today the best ROI GPU is R9 280. :)
Other selection criteria:
Checking the hash rate using different algorithms. There are many altcoins that use different mining algorithms. Moreover, some coins even know how to switch between different algorithms, thereby complicating the work of ASICs. It is recommended to choose a video card that shows a good hash rate on one of the popular algorithms, where you can mine an alternative coin in case of failure with the main choice.
The ability to install multiple video cards at the same time. Even home mining continues to live in 2021 using just one video card. The miner's strategy in this case is to get a coin and postpone it until the rate rises. But gradually this strategy is becoming a thing of the past, and mining on a separately assembled rig, where you can install many video cards, comes to the place of mining with the help of a home computer.
Store or secondary housing
Most often, buying a video card is much more profitable in a store, since a video card purchased on a secondary can fail at any time. But at the moment of Ethereum's transition to PoS, one must remember that a number of miners throw their old cards onto the secondary market, refusing to mine new coins.
The cards could hardly have been used before, so the probability of their breakage is extremely low. An additional advantage is a high hash rate, because the card was specially bought for mining. If you intend to buy a video card on the secondary market, it is better to do it as soon as possible, then the price may rise again.
