It is called premarket or so. I have tried it before when it was common or probably when I noticed it last year. At the time, Telegram tokens were common and some of them were in the premarket. That was when I knew that premarket is very dangerous. I remember coins like hamster combat fall significantly after it was launched and its price dropped far more than the premarket price. There were also some other ones like that. It is still about luck and not that premarket will give an opportunity. It is very possible that some will increase in price.
Ohhh more like a presale, yes i can remember well that it was done in the Ton boom era, the future too seems like the same concept
