I think the success of the ICO has ended in gaining huge profits, very few ICOs so far have only focused on getting profits for themselves, for me it is no longer suitable for investors to join, there are only a few pure ico in developing it. success needs to be an active and transparent development that has an experienced team and definite support
We cannot conclude that it has ended finally we might be having some challenges right now which was caused by the influx of scammer that infiltrated the ICO industry, but we can't because of that give up completely on the very good ones that are available, and the developers can also not because of that give up on showcasing their projects.
In every eggs that is in a create of basket, there would always be a bad one which normally, you may not know until you get to break it, but there are some people that has developed a mechanism which you can use to know the good one, so all we just need to do is come together and start thinking out of the box on how we can chase these bad projects out and how the scammers can also be dealt with.
