IEO now has so many good bounty campaigns and you can earn from them
IEO have no guarantee of success. Some teams participate in the IEO after the failed ICO 2017-2018. The only plus is the authority of the exchange, they have to choose the project themselves for publication and it's reputation at stake.
You said that their reputation is at risk but you also said that ieo have no guarantee ? What the ? Are you confuse ? Ieo is more guaranteed actually because the exchange reputation is at risk , binance for example but its still risky if you will invest on unkown exchanges that do ieo . so what if the ico teams have failed and migrated on ieo ? There is no problem with that . maybe they the reason why they failed is because they lack of investors and not the other way around .
There is actually no guarantee expressed when we are supporting a project. However, we know that IEO compared to the usual ICO means that it is safer (or less risky) all because we are dealing with the exchange here directly and that we are assuming that the exchange is doing its vetting process well so that they don't deal with any scam project...but as to what will happen along the way maybe the exchange will not anymore make any hint on that as those can be depending on how good is the team behind the project.
For sure which exchange would really have those criteria before choosing up a project which would be accepted to launch up an IEO.
Projects reputation will really affect on exchange reputation too thats why they would really be keen on selecting which project would able to
pass through.When it comes to investment risk level then we do know that IEO is better than traditional ICO.
