49 bought the pump 66 run, 45 began to buy the handicap too poorly and was forced to eat 49, no short and long back and forth, otherwise you can make more. There are several reasons why it is not a pre-sale to mainly do secondary level One is the experience of the monkey land period, I had a studio at the time, and I was very tired of doing a lot of monkey land, and in the end I didn't make a lot of money by opening a lot of ape after selling the monkey land, so I remembered the experience of that time, and I felt that it would not be bad to focus on the second level The second is that the pre-sale strategy I chose was to go to Kraken and felt that I would not be able to roll, but I was forced to go to the second level to grab funds by the capital. Looking back, it's a good thing that there is no pre-sale, otherwise it is difficult to hedge whether to hedge or not, and the income may be about the same. That's the end of the summary, let's continue next time.
