The issue is that many of the upcoming ICOs keep on repeating the mistakes of the predecessors and that's why we're where we are now. same talks, same brags, same cheat, same lack of project development etc etc. Buh I believe as times goes on, we'll be settling on the better ones to clinge to.
Now the biggest mistake is to do ico, very few of the projects something collects and develops further, I think it is now more popular to do more ieo, here funds can be collected and then recently the decline in ieo
