Today I participated in Binance's TGE at the last moment, and I saw a 210x return, so I got in. The profit was roughly around 100 as I had thought. I forgot to adjust the gas at 101, so I couldn't sell, and it only executed at 82. Basically, it can be concluded that as long as it's around 200x, it's about 100u; if it exceeds 200x, then it's better not to participate.
