Actually, it's good for everyone to argue online, otherwise the cryptocurrency industry would have been forgotten. I have publicly stated that I only have some link tokens, and I have also mentioned in the subscription section that I did not sell them much from a cost of 7 yuan to 30 yuan. Now I use it as a Happy Bean to practice technical analysis and do grid work like playing a game. Now I have increased the cost to about 5 yuan, but I no longer expect it to increase many times as much as I did in the past. The effect of creating wealth in the cryptocurrency industry has basically disappeared. On the contrary, many AI semiconductor and optical communication companies have seen a 5-10 fold increase in market value since the middle of last year, which is even more magnificent than the counterfeit season of that year. Although a little unwilling, as a fisherman, the first principle is to go fishing in places with fish. Link was recommended to me by my husband. Today, I flipped through his reading notes on the 2017 Ethereum White Paper on my computer. He is always curious about all new technologies, but never thought about monetization and its consequences. Now thinking about it, what's the use of not applying too much knowledge? So after the AI wave came, I asked him to use it for investment analysis and in-depth analysis of semiconductor companies, in addition to researching AI for self entertainment. I think there's no need to regret missing any era, there will always be a new era. Live longer, there will be a few big opportunities in your lifetime.
