in 2011, butrin began to realize bitcoin under the influence of his father when he was 17 years old in high school. Butrin showed a strong interest in this new thing. In order to better understand this fully distributed currency, butrin began to read bitcoin forum and technical materials. He wrote bitcoin blog articles to earn bitcoin, although his hourly salary was only $2 an hour
when he made 20 BTCs, he took 8.5 to buy a shirt. But he realized at that time that if thousands of people from all over the world join the bitcoin community, an independent financial system can be created, and the application of blockchain is not limited to cryptocurrency, but applicable to all walks of life. Since then, Butlin has been working in this direction
in late 2011, butrin graally became famous in the community. A man from Romania invited him to co-founder bitcoin magazine and serve as the chief writer
in short, bitcoin is a virtual currency . Like stocks, it can be invested and traded. In technical terms, bitcoin is a kind of P2P digital currency
but after all, the nature and mode of bitcoin is different from other currencies, and it may prosper in the future. It may also be like the collapse of the economic bubble, which is unknown. If you enter the bitcoin market and have a quarrel, it will not become a real currency, because the fluctuation of the price is impossible to satisfy everyone. If there is a profit, there is a loss. Therefore, the investment of bitcoin should be cautious. If you don't fully grasp it, don't try it easily
the climate is hot and humid in summer. When people sweat in hot weather, the watch may leave green or black marks on the wrist when it encounters sweat. Due to the different pH value in sweat, the degree of clock erosion is also different. Therefore, it is an important issue for watch lovers to take the initiative to maintain their watches
watch maintenance in summer
the reason why the watch turns green with sweat is that the watch factory adopts gold-plated copper-clad plating which is easy and beautiful in color, but if the gold-plated technology is not handled properly, it will cause the watch oxidation. Nowadays, PVD stainless steel plating technique is widely used in gold plating of watches and clocks, so it is rarely found. Therefore, it is recommended to buy stainless steel or K-gold materials. As for the problem of wrist blackening when wearing a watch, it is directly related to poor air quality and st stuck in the watch strap for a long time. In this case, it's best to give it to a professional watch shop for cleaning. You should also pay attention to the cleaning of the watch when you wear it on weekdays.
