My own reasons why I think IEO is better than ICO
1)IEO projects are legits ,scam free but
i) don't always expect the IEO tokens to double after IEO instant sell out ,many are complaining about IEOs losing value I think this is possible and normal too
2) IEO is here to fix scam issues only don't expect that all IEO will be a success on the long run,they might still fail but far from scam like ICO projects
3) it's wise to do better research even if the IEO is launching on binance ,don't just invest because the IEO is from popular Exchanges because what the project is introducing might not even make lotta sense
With IEO, the team doesn't need to spend too much advertising to create awareness to investors.
Although, some popular exchanges may required more budget to list IEO.
The point no 3, usually peoples will prefer to join IEO from popular exchanges, because the exchange reputation is good.
