One's own learning, work, thinking, and operation can all be contextualized. When I was running an airdrop studio before, I was completely new to the training. I recorded about 9 classes, all of which were played in the small universe. Each class lasted about an hour. After these 9 hours, the novice completely understood the cryptocurrency market. Now there are two or three studio members with around 70000 fans, and it is said that the monthly advertising revenue is between $2000 to $3000. I used the methods I mentioned during the training. Now I read 10 classic trading books with my group friends every year, and I have started recording my reading process as audio again. I believe that while reading, I can recall my past experiences in encrypted trading. This type of audio is very valuable, and I can sell recordings like Wu Yongda in the future.
