In the past few years, the graphics card industry has become very popular due to mining, so purchasing the favorite graphics card is not only expensive but also difficult for ordinary users and gamers.

Ethereum has completed its merger and the era of large-scale graphics card mining is over. How to regulate mining cards on the market?

?1. Ethereum has completed the merger. Today’s graphics cards are not just for mining. Let’s say that the biggest change must be the Ethereum graphics card. The Ethereum Foundation stated that the merged Ethereum network will run entirely under the proof-of-stake algorithm.

PoW mining is no longer possible.

The Ethereum blockchain will no longer be operated by miners’ computers and graphics cards, but will be verified by validators.

The successful completion of the Ethereum merger has also brought a huge impact to the mining card market.

The demand for GPU mining machines seems to have shrunk, and a large part of the mining machine market no longer focuses on GPUs.

Prices for some GPUs have also dropped rapidly, now down to between $500 and $600.

2. How to regulate mining cards on the market?

It is impossible to regulate the mining card market now, but we can prevent being cheated.

You can tell whether it is a mining card by looking at the back of the graphics card core through the Internet. In fact, this is not reliable.

Some people say that it depends on the capacitor. SMD capacitors are all yellow, so it is useless to look at this.

It is also difficult to tell whether it is a mining card or not by looking at the color difference of the PCB.

The power supply of a graphics card that has been used for a long time and the PCB on the back of the core will also have color differences with low-temperature areas.

Unless it has been out of the factory for a short time, but the color difference is particularly serious, it can be judged as a mining card.

Of course, there will definitely be dealers who cheat, but you still have to be confident and see clearly.

3. How to prevent buying mining cards?

When purchasing a second-hand graphics card, it is best to ask the seller to provide an invoice. Only the invoice can ensure that the graphics card enjoys the nationwide joint warranty service during the warranty period.

If the seller states that the graphics card is not under warranty or only supports in-store warranty, then there is a high possibility that the graphics card is a mining card.

Generally, miners will set the price of the graphics card below the regular price when selling mining cards. If the graphics card is much lower than the normal price, then the graphics card is probably a mining card.

Don't be greedy for small gains, otherwise you will lose everything.

Postscript: The biggest problem with buying second-hand products on online platforms is that you can't see the actual card. It's difficult to judge the quality of the card, whether it can be lit, etc. with just a few photos.

If you are not careful, you may buy a slag card, and you may even be unable to light it up after you get it.

Go to the seller to argue. The seller also has various reasons to dump the blame.

So finding a reliable seller can solve many problems. I hope everyone can buy a good graphics card.
