Well, no one is saying there are no projects out there that can end up doing well in the long run, but one thing for sure is that as long as you know what to always look out for when it comes to a project, you will always be in the right mind to make decisions when it comes to such.
We all know the best way to always identify a good project is to try as much as possible to make sure you check out the team, the product and the business they are bringing to the table. However, all these things don't usually mean that it all will just end up making giving you some huge profit immediately and some won't, but like someone said, investing in ICOs is more or less an educated gambling.
