not all IEO will give you profit, some IEO end badly and experience price declines when they start trading. for that, keep doing research before you join because the IEO also has a huge risk
There is no kind of investment is easy to get profits, includes IEOs. You are right my friend, but I would like to emphasize that most of IEOs give investors losses, there are only minority of IEOs give investors profits. They are rare and mostly come from big exchanges. IEOs is not the place for you to gamble, because you might get losses.
