On September 15, 2022 local time, Ethereum co-founder Vitalik Buterin posted a statement saying that we have finally completed the merger of Ethereum! It is reported that the transition from Proof of Work (PoW) to Proof of Stake (PoS) on the Ethereum mainnet is called "merger", which also means the end of the era of large-scale graphics card mining.

This mine tide lasted unprecedentedly, and the number of mine cards flowing into the market after the mine accident will also be unprecedented. So, will the prices of graphics cards on the market return to normal? How should we prevent mining cards on the market ?

1. Phenomenon: After the merger of Ethereum, the long-term dependence on traditional mining models ended

We must know that Ethereum has been on the long road from proof of work consensus protocol to proof of equity pledge. Now that the Ethereum merger has occurred, this is actually a mechanism to eliminate Ethereum mining incentives to support pledge. In fact, the cost of pledge is not small, estimated to reach more than 300,000 yuan, and a punishment mechanism has been introduced.

• Overall, after the merger of Ethereum, GPU graphics card mining faces dark days. The complete switch between Ethereum cryptocurrencies and shifts to the "Proof of Stake" algorithm ends Ethereum's long-term dependence on traditional mining models.

mining difficulty of the Ethereum blockchain has been steadily increasing in the past time because the total number of GPUs actively mining ETH around the world has been increasing. The more participants, the more fierce the miners compete.

Interestingly, in June 2021, the difficulty of miners' mining declined sharply because we began to ban cryptocurrency mining. In mid-2021, the cliff of mining difficulty has decreased, and we should thank China.

• One of the reasons why China bans mining is the pressure it puts on the power grid, and there are more and more power shortages in various places. In the end, the miners who had an unhappy relationship went to the court, but they were still disappointed.

's most famous story is the JD graphics carmen that year. JD customer service said that it does not support graphics card returns, because the customer service found that the mining miner's door purchased graphics card and used JD's self-operated 7-day return loophole to swipe the card and then return it after swiping the card to mine.

can be seen that with the end of the mining era, all "noisy incidents" of absenteeism will eventually disappear.

2. Analysis: The difficulty of mining will soar, mining becomes meaningless, and even loses

. There is no doubt that graphics card mining is completely cold, which also means that the mining tide that lasted for nearly two years is about to end. The parties will win a great victory and we all win. After the merger, there are two forks: one is etf and the other is ethw, but these two are basically no profit and the earnings are far from enough electricity bills, so the fool goes to dig.

also has ETC. Based on the current 3060Ti, which has the highest energy efficiency of than , at the electricity price of 0.3, a 3060Ti earns only 0.39 yuan per day to an 8-card 3060Ti, and you can actually earn a bottle of Coke every day.

• If calculated based on the electricity bill of 0.5, the daily income of a 3060Ti will be -0.21! It is purely lost, and the electricity bill cannot be earned back. The more you dig, the more you lose, the more you lose, the miner will be completely G this time.

Personally believe that after the big merger, miners will probably have two ways to go:

One is to close the deposit without profitability and cannot afford the electricity bill and consider selling graphics card GPU. Ethereum mainly uses GPU for mining, and it is understandable that it has always been valued. Ethereum mining is so profitable that no alternative can provide close to the same level of compensation.

Second, although after the merger of Ethereum, its power consumption demand has decreased by 99.95%, which also means that cryptocurrency miners are reluctant to use their graphics cards to generate Ethereum. On the contrary, miners are still likely to accept other exploitable virtual currency , which is much lower in value.

But no matter what, it is certain that Ethereum mergers are always good.

3. Solution: How should we prevent mining cards in the market?

It can be said that all cards that can be mined such as 30 series and 6000 series are mined cards by default.I would like to remind those who don’t understand the situation that these cards only have mine and personal mine cards, and there are no non-mining cards.

The large number of factory reprints that have been exposed have already lost all the consumers' most basic trust in the manufacturer. So it’s right for your default mining card in the 20-series 30-series. At this time, a handsome 750ti passes by and says: 750ti, I can fight for another 3 years.

• That is to say, as the wait and see year after year, the market gradually returned to rationality. Even if the price was reduced, I was still indomitable and could wait for another 3 years. But if you really want to buy it, how can you prevent mining cards?

It can be said that there is no effective means to prevent mine cards, and you can only buy a mine-free card model to avoid mine cards 100%. For example, the upcoming RTX 40 series and the entire RX7000 series will be released; there are the 30 series variant 3060 8GB, 3060Ti GDDR6X versions released next month, and the 6X50 XT series released by AMD.

Of course, if you buy a new card, it is recommended to wait for the 40 Series/RX7000 Series new card, because the cost-effectiveness of the new card is much higher than that of the 30 Series and 6000 Series variants. After all, these variants are purely disgusting.

If you pursue cost-effectiveness and don’t mind mining cards, the price of graphics cards will not return to normal for a long time in the future, and a significant discount is the norm.

• However, it is recommended to purchase all second-hand cards by default. Unless you know the person who sells the card and knows that he has never dug a mine, you should buy it as a mine card. You can buy a mine card. As long as the price is reasonable, don’t think you are lucky and encounter a non-mineral second-hand card that you use. If you have this luck, it is more reliable to grab the original price of 40 series.

Finally, after the mine accident, it is expected that very cheap whole machines will appear on major online store platforms. The whole machine chamber will recycle a large number of low-priced mine cards and sell them in the form of whole machines. This is the hardest hit area of ​​mine cards, so be careful.

Last words: We thank the mine boss, which is equivalent to "destroying" the entire PC market

In short, for me, 50 charges 3080, and 100 charges 3080ti, it is regarded as charity. Miners don't need to rush to swear me. More than 20 million mining cards are now a buyer's market. I am not a big mistake. If you like it, you will sell it. If you don't like it, you won't sell it.

• mining actually gives Nvidia AMD a very good market, but this thing will definitely end one day. Insufficient consumption is a problem that the global market will face in the future. Nvidia and AMD have made a lot of money. It is time to let electronic products return to their due value.
