yes I prefer investment using IEO which makes me reliable, but it depends on each in choosing the project. according to me it is very good. because in using the IEO to avoid project scam and fraud
Well you can always check IEO on binance, because i'm sure binance only choose a good project to get an IEO on their site. Not all of them are a good project but mostly are good.
IEO advantage is it's easier to buy, more cheaper (transaction fee) and also investor don't need afraid.
