Actually investing in the project is not wrong, it's just that we have to really know that the project is a project that has real benefits and has a lot of interest in all sectors, so the possibility of being cheated will be very small if everything goes smoothly.
if you still want to participate to become an investor in a project then I suggest you to participate in an exchange that offers IEO projects because the IEO organized by the best exchange places such as Binance will provide very strong support and will certainly run out quickly because many interested people.
IEO projects are fine but you have to make sure it was on a high reputation exchange cause if it was on a scam exchange, IEO won't be a saving point. Binance is the best out there but not many projects can IEO on there, tho.
