I once participated in a a certain project that was giving Investors about 5 times (5×) bonus during their presale.
It's so easy for them to give the investors bonus during presale but is it worth it at all for you? For the risk of getting scammed or the price isn't something that you are comfortable with because most of the projects that are currently in presale are pretty much could end up in same scam scheme with whatever reasons they could come up with or not.
The team kept postponing the exchange listing date until everybody got tired of them and realized that, it was a scam project.
It's a classic reason for them, I bet they don't even bother to make a listing proposal at all.
When the complaints on the Telegram group became too much, the project team just abandoned the group, leaving Investors with bot.
Always to check the members everyday and if possible just avoid investing in new projects for now, it's not worth it.
