Record several recent pre-sales and summarize their patterns one ️⃣ The first hot pre-sale was SKYAI from @ four_mame_ -Participation level and PNL: I worked hard and played more than ten accounts, but sold early and earned 70-100%. I earned nearly 3 BNB per account --Reason for participation: Directly endorsing the pre-sale of the first official endorsement on Four --Reason for making money: Official endorsement, representing Bsc AI's first attempt, there is a certain opportunity for the design of single number hardtop --Post opening situation: 70->20->70 two ️⃣ The second hot pre-sale is on the third floor, with actress coins -Not involved --Reason for not participating: Actress Coin has no history of rising, avoiding pitfalls --Post opening situation: Half cut at the opening, later given a chance to recoup, now zero three ️⃣ The third hot pre-sale is Mirai -Participation level and PNL: Worked for 200 sol, not yet launched, refunded half, waiting for opening, PNL unknown --Reason for participation: I was the first to launch a new product on the Holoworld platform and subscribed to a well-known Japanese virtual human project. The Holoworld platform has launched successful projects before --Not yet opened four ️⃣ The fourth hot pre-sale was just 10K -Participation level and PNL: Worked for 200 sol, cut all the meat, lost 80 sol, 100000 RMB, I don't know how many years I can live --Reason for participation: Pure imitation disk, sol forwarding, names all competing with LAUCNCoin, there may be some people buying this because of missing LAUCNCoin, and there may be emotional hype --Reason for loss of money: The project team was born, and the soft rug who shouted orders with their mouths was successful four times. It is unlikely for consecutive entrepreneurs to pay for it, making it difficult to get it into their pockets --After the opening, the situation: gave a one minute chance to recoup the investment and run away, but the leader left first and then smashed it to near half Teacher Lu and his group members said, "Indeed, the founder of this failed soft rug should give up. With such a large pool, this is all a contribution to those who watch videos. Every day, one video is airdropped at a cost of 100000 dollars Summary and Review: The most important thing is the outcome of stealing -I analyzed it for my group members the first three times, but I didn't analyze it for the fourth time. When it came to the end, I remembered that I had worked 200 sol and lost money. This is the end of stealing 2. When there are too many failed experiences, one should avoid pitfalls and conduct more analysis on the project itself -The mechanism of the 10k platform itself has problems, and the reasons for the founder's failure are varied. From the perspective of preventing emotional hype caused by stepping into the air, the self-defense position should be reduced to a lower level 3. Successful participation is determined by the endorsement value of the project itself. In terms of endorsement gold content level analysis: -Creating new products on the platform is the biggest endorsement -Forwarding and reposting may usually only be for the support of ecological projects, without endorsement, and the operation may not have undergone strict background checks ——Other failed cases include an unorganized event project on Sol that was forwarded in an orderly manner and forgot its name. Most projects that rely on referral as an endorsement have never been launched Future pre-sale strategy: I won't make any more money Successful pre-sales have also given opportunities for the second stage after the opening, such as Pain, Skyai, Slerf, and Bome, which are typical examples of trading opportunities that still exist after the opening. This time, 10k originally wanted to take a wave of emotional arbitrage with launch coins and left, but ended up burying the principal in it For projects like this that do not have cost-effectiveness, consideration should be given to intervening after the opening. Today, dev taught me another lesson
