My adventures in the currency circle

One day in 2012, a 40-year-old boy was happily surfing the Internet. He surfed and surfed, and suddenly a message came: "Bitcoin has risen sharply, from 0.1 US dollars to 10 US dollars." What is this? I seem to have seen this name in a magazine before, but I didn't pay attention. Is it the same as Q coins? Why did the price increase? So I frantically searched for information on the Internet, which led me to the only exchange in China at that time, BTCCHINA. I saw that the price of Bitcoin was 125 RMB per piece. I quickly bought 10 to play with it. I seemed to have discovered a new world. It turned out that this thing was so fun. The price was rising every day. In 2013, the unit price rose to 5,000, which was very crazy. At the same time, it also made me despise my normal work, which caused a lot of impact.

Because I am a tech geek who made a living by repairing video recorders in the 1990s. I have a strong interest in electronic circuits. After understanding the principle of Bitcoin mining, I must make a Bitcoin mining machine. There were no special mining machines in that era. Everyone used CPUs or graphics cards to mine, and the difficulty was still very low. The most advanced technology is to use FPGA chip programming. As a mining machine, it consumes much less power than graphics cards and is not expensive. It’s just that you can’t buy ready-made machines, so you have to make them yourself. At that time, there was a big guy, I think his name was Baked Cat. He was very good, and he also had a set of FPGA information that could be obtained for free on the Internet. I didn’t expect that I, who was very good at hands-on skills, could make it, haha. Shenzhen SEG’s blank FPGA chips had to be snatched, and I finally snatched 100 pieces. The process of making a machine was very painful. The difficulty of Bitcoin would be adjusted every 14 days. Because a large number of machines entered the market, each difficulty adjustment was a leap-forward, and every day of delay in entering the market was a loss. Waiting for components, circuit boards, and chips, and debugging each piece, time is really money. My hair was all white at that time.
Please take a look at my finished product:

Later, I continued to mine in f2pool and mined about 50 BTC in total.

But it is easy to look at the past, but difficult to look at the future. In the following years, Bitcoin experienced several ups and downs. Due to my short-sightedness, I didn't hold on to these coins after all. Looking back now, if I had the spare time to make some mining machines at that time, wouldn't it be better to just buy coins and hoard them? The current price has reached the point where I can't afford it, and except for this original Bitcoin, all other coins have no collection value and can only be used for short-term. This is my personal understanding, and it may be wrong. What is destined to happen will happen, and what is not destined to happen will not happen, Amen.
