there are so many ICO's out there now that it's really hard to decide which one is good and which is not. I completely understand your confusion and trust me it's normal. It's hard to forecast which coins will have future potenial but try to do the following. First of all read the whitepaper and determine if the idea and solution the project is offering is any good. Is there a market to be served for that idea or product and are there any competitors who might have already developed a similar or even better product? Second check out the team, are they available on chats and are they engaged with the community? How are their past experiences compared to what they want to build. The ICO has to have good terms as well, fair distribution and a large user base/fanbse. It will take some time until you find a good project and it involves a lot of research, but you'll be handsomely rewarded if you find a good one.
