Let's review @uptopmeme. Although I only got a little, at least the approach was correct.

1. Prepared a day in advance, thought through the response strategy and approach.

2. When it started, I was focused on the blockchain, and I heard some friends were focused on the webpage, but the page froze. Those who were watching the blockchain got the correct CA and hexadecimal numbers first. I configured the software by 03 minutes, and it finished at 06 minutes on the blockchain, barely catching the last train.

3. My success rate for this purchase was only about 30%. The biggest mistake was being lazy, too lazy to set up so many RPCs, resulting in a lot of RPC errors and a significant decrease in success rate.

4. Didn't get rich, didn't obtain much.
