I would like to return Neither ICO nor IEO, cause both of those are dangerous way even scammers still grabbing money by using those ways.apart from those things, new technic come in market, which is called defi. After old scamming technic Ico & ieo, scammer start defi technic and as a reaction of that, very terribly downfall of defi tokens happened within night.although ieo is good technic than ico, cause if ieo token scam, you may sell your token & recovery little money but no chance to Recovey from co token scam.
Difference with IEO is that these coins would really be directly be traded on an exchange that's why when it comes to security or assurance then IEO is the best one
among the 3. Less risk but still not guaranteeing that you would really make out some profits.
In talks about new hypes and methods of sales then I wont really be surprised if we would see another one comes next to DeFi.
whenever which things come then tendency of scam or losing money by the investors is inevitable.Scammers are always there
which would really be fooling out people to scam out.
