There are clearly a lot of people trying to raise funds for ideas that are far from unique or very good. I think the main problem right now is that a lot of ideas are just old school business models where blockchain/crypto are being added without any innovation. For example, you want to launch an crypto business copying Amazon - what is the point, if crypto becomes the preferred payment option in the world Amazon will accept crypto, and your site has nothing - because you did not invent anything new. Blockchain enables us to reinvent businesses, why copy them? So when you invest, look for innovation. Innovations will take your potential ICO list down by 50% at least, dont invest in a project that do not reinvent, copies will always fail.
