In the field of digital currency, Bitcoin has always been one of the focuses of attention. Recently, the difficulty of Bitcoin mining has hit a record high again, and this news has boosted the entire industry. At the same time, the prospect of the return of mainstream mining machines has become distant. Let us explore this phenomenon in depth to reveal its inherent logic and impact.

The surge in Bitcoin mining difficulty means that the computing power and resource costs required to mine Bitcoin have increased significantly. This change stems from the mining difficulty adjustment mechanism set by the Bitcoin network, which aims to keep the mining speed stable. As the participation of miners around the world continues to increase, the difficulty of mining has naturally risen. In this case, it is difficult for traditional mining machines to adapt to new challenges because their computing power and efficiency can no longer meet the growing mining difficulty.

As the difficulty of mining continues to rise, the prospect of the return of mainstream mining machines has become increasingly slim. The once prosperous mainstream mining machine market is now facing severe tests. Many mining machine manufacturers have to re-examine their product positioning and technology research and development direction. For example, well-known brands such as Bitmain and Antminer have launched a new generation of high-performance mining machines in an attempt to cope with the surge in mining difficulty. However, even so, the future of mainstream mining machines is still full of variables, and it is necessary to find a balance between technological innovation and market demand.

In this challenging moment, miners are also facing unprecedented pressure and choices. They need to weigh the relationship between input and output, and decide whether to continue using old mining machines or upgrade to adapt to the new situation. There are many difficult choices and risks. Some small miners may even be forced to withdraw from the market due to the surge in mining difficulty, which will have a far-reaching impact on the entire industry.

However, even in the face of many difficulties, the innovation and resilience of the digital currency field continue to play a role. With the continuous evolution of blockchain technology and the expansion of application scenarios, people's views on digital currencies are gradually changing. Although Bitcoin faces challenges, its status as a cryptocurrency remains unbreakable. In the future, with the advancement of technology and the adjustment of the market, new opportunities and possibilities may be born.

In general, the record high difficulty of Bitcoin mining and the situation where the return of mainstream mining machines is far away have brought profound thinking and challenges to the entire digital currency industry. In the face of future uncertainties, we need to keep an open mind and actively respond to various possible changes. Only by continuous learning and adaptation can we remain invincible in this field full of opportunities and risks. May we witness the vigorous development of digital currency and welcome a better future.

According to BTC.com data, the latest block difficulty adjustment increased the difficulty of Bitcoin mining by 3.45%. Although the increase was lower than the last 9.26%, it was the fourth consecutive upward adjustment of the difficulty of mining, which also made Bitcoin mining difficulty hit a new record high. The current difficulty is 32.05T.

Bitcoin mining difficulty represents the difficulty of miners to produce the next block. It is adjusted every 2,016 blocks. The purpose is to maintain an average speed of 10 minutes to mine a block through computing power adjustment, which is carried out about every two weeks. Therefore, mining difficulty can also reflect the degree of competition among miners. The lower the mining difficulty, the less competition.

Bitcoin mining difficulty increased by 3.8%

The heat wave cools down, and the computing power continues to recover

Originally, the mining difficulty hit a new high in mid-May this year, but the heat wave hit the United States, and miners in Texas, the United States, frequently shut down to respond to the call of the Electric Reliability Council of Texas (ERCOT) to reduce power consumption.

Since most of the US cryptocurrency mining business takes place in the southern states, the heat wave not only hit miners in Texas. Jason Mellerud, a senior scientist at Arcane Research, said: Due to the extreme high temperature that caused the electricity price to soar, US miners have shut down their machines for a long time in the past two weeks, which has slowed down the growth trend of electricity bills. Recently, after the heat wave temporarily cooled down in some parts of the United States, Bitcoin mining companies have restarted mining operations and added new facilities to increase mining power, which has also made Bitcoin mining difficulty hit a new high again. The adjustment of mining difficulty also seems to mean that miners are gradually returning to the team. According to BitInfoCharts data, the total computing power of Bitcoin has now recovered to 288EH/s, an increase of 196% from the lowest level of 97EH/s in mid-July. Miners' profits continue to decline

As the overall economy is affected by the high inflation environment, the price of Bitcoin is still stagnant at the level of 20,000 US dollars. As the difficulty of mining hits new highs, the competition among miners heats up. For those who make a living by mining, they will face the dilemma of shrinking profits. According to f2pool data, at $0.1 per kilowatt-hour, there are only 8 mining machine models that are still profitable. The Antminer S19
XP Hyd. model is the highest, with a daily profit of $7.42.

The mainstream model Antminer S19J only has a daily profit of $0.81. Compared with the official price of Bitmain at $9,984, it is a long way to go to get back the investment.
