1. I don't buy bitcoin, so I buy ten mining machines with a monthly profit of 10000 yuan

2.

development trend: the divergence of development teams leads to the bifurcation of technical routes

the most criticized problem of bitcoin is the small block capacity, which is only 1MB. As a result, bitcoin is becoming more and more unsuitable for trading. Many transactions will not be confirmed immediately after they occur, and many blocks need to wait, so the transaction fees of bitcoin are higher and higher, Obviously, it will be further and further away from the idea of a trading currency

for the problem of bitcoin block capacity, as the founder of bitcoin, Nakamoto Tsung has given a solution. The size of the earliest bitcoin block is designed to be 32MB, and the roadmap of bitcoin expansion is given. The reason why the bitcoin block was limited to 1MB in the early days was to prevent the network congestion caused by a large number of small transfers in the early network

however, bitcoin did not upgrade as it should, but still maintained a block size of 1MB. The reason is the divergence of the bitcoin development team. Nakamoto was the developer of bitcoin, but later retired and left the development task of bitcoin to the bitcoin development team. However, the development team was very different about removing the 1MB block limit, so the development team split up. The original development team (core) wanted to continue to limit the size of 1MB, and the people who left formed other development teams (several), It is also called large block team or support expansion team. In the end, the two groups failed to reach a consensus on the upgrading of bitcoin network. A new bitcoin, bitcoin cash, was created, which is different from the original bitcoin. He inherited all the blocks (transaction records) of bitcoin before the split, but after the split, he used a new block of 8MB, which is different from the previous bitcoin (BTC, developed and maintained by the core team)

there should be three types of hard bifurcations for bitcoin, including the cash bifurcations for bitcoin (uahf). The original bitcoin network is prepared to implement segwit2x, which is the bifurcation scheme of the New York consensus. However, e to opposition, segwit2x was not implemented in the end, maintaining the original bitcoin path. But bitcoin still needs to be upgraded. The emergence of bitcoin cash is not accidental. In fact, there are other bifurcated bitcoin coins, such as bitcoin limited and bitcoin old. It's only because of the problem of popularity that it doesn't enter the public view. Now bitcoin cash is the most competitive bifurcated coin

In the Shang Dynasty, the Zhou tribe was founded by the father of Gu Gong, the 12th grandson of the Yellow Emperor. The king had three sons. Ji Li, his youngest son, was very talented. He gave birth to Jichang (King Wen of Zhou). When Jichang was born, Shengrui appeared, so the king preferred Jichang to take over the throne. Taibo, the eldest son of Taiwang, and Zhongyong, the second son of Taiwang, knew that their father meant to pass the throne to Jili first, and then to Jichang, so they decided to give up the throne automatically, and they went south together to jingman. Taibo and Zhongyong brought the advanced culture of the Central Plains to Jiangnan, which was relatively backward at that time. They were elected by the local aborigines as the king's chief, known as the king of Wu. After Taibo died, Zhongyong succeeded him.

Too much delay, not objective at all. I've been in this instry for many years, and my general answers are as follows:

I. old international brands : hesman, Gretel, Roderick, Mosa . The following four companies are introced respectively: hesman, Gretel : they were acquired by Baitong long ago, and then R & D was cut off. The biggest advantage of the equipment is stable point, but the disadvantages are also obvious, such as old components, unable to update software, new models, etc< Roderick : after being acquired by Siemens, the quality of this company is relatively average, and there is no bright spot. But it's selling well with Siemens' strong market< Mosa : the quality is medium, but the price is cheap. It's sold well in the past two years. Compared with previous manufacturers, the only one with R & D team

Second, domestic brands : Dongtu, Sanwang, Haide and others
Dongtu and Sanwang : why introce them together? Because their development process is too similar, they don't pay attention to technology, but there is a big market, and many equipment are OEM from poor small factories, Therefore, after a serious accident occurred in the rail transit instry in eastern Turkey, it is now banned from the rail transit instry by the state
Haide : This is a very strange manufacturer, different from all domestic manufacturers. He started his business as an agent of hesman, and he also maintained a domestic brand called hesco, but he also went to small factories for OEM, so he had no R & D strength. But he and hesman once set up a research and development team and introced some hesman technology, which was once very expected. Unfortunately, he gave up halfway. The research and development team left to set up a company specializing in instrial switches. Haide is still moving bricks and sticking labels
other small factories : there are a lot of domestic instrial switch manufacturers, but most of them rely on OEM, and there are few independent research and development, resulting in poor quality. If you want to use domestic procts, you should choose those with R & D team

In the Shang Dynasty, the Zhou tribe was founded by the father of Gu Gong, the 12th grandson of the Yellow Emperor. The king had three sons. Ji Li, his youngest son, was very talented.

2. The surname Wu existed in ancient times. One is that some descendants of Shun were granted the title of Yu.

The king of Zhou wanted to pass it on to Chang, but according to the tradition at that time, it should be passed on to the eldest son, so the king was depressed. After Taibo understood his father's meaning, he fled to the desolate south of the Yangtze River with his second younger brother Zhongyong, founded his own foundation and established the ancient kingdom of Gouwu. After the fall of the Shang Dynasty, the Zhou Dynasty was established. King Wu of the Zhou Dynasty appointed Zhou Zhang, the third grandson of Taibo, as Marquis, so he changed the name of the state to Wu. In the spring and Autumn period, the state of Wu was destroyed by the state of Yue.
