The market pattern is changing at the moment and instead of just ico's there has also been IEO and STO, which have also proven to be more effective than the ico.
The advantage of the security token offering is that only accredited investors who are capable of investing in security projects will be able to invest thus saving the project from security-related regulation and for initial exchange offerings (IEO) investors do not have to worry about the when to list on exchange as most of the time trading will start immediately after the fundraising so these are both in a way better than the initial coin offering that is common previously.
IEO looks similar to the ico that already launched through use the exchange launch pad system. But that depends on the exchange site itself dude. If that was a good exchange and it can handle properly.
