only if it is solid and famous exchange like binance. on binance every ieo make for it's participants profits. few times i read it is x3-5 in the start of trading. only those who have money can participate.
There is no guarantee that you will get returns all the time with IEOs in Binance. It is true that exchanges such as Binance and Huobi screen the IEOs very carefully before listing them. But then, market dynamics can also have a big impact on the future. So when you go for the investment, you need to craefully analyze all the factors about that particular project.
yeah you should understand that neither of exchanges does not take responsibility for listed IEOs
I mean they partially do, but its not that crucial for them if one or two projects could be a disaster
