Yes. There are still ICOs out there with great potential. Diligence is a must. DYOR always so won't get the scammed.
Really, why now? A lot of projects have already brought to their investors good money. You can pick great ICOs which are listed as the best ones on the trusted sites. Just look through this site, for instance:
https://icorating.comas long as we can find a good ICO, then it still worth to invest in ICO. but right now, it's too difficult to choose the right ICO as there are many of the ICO stop their project and some of them are scam people and run away from the project. but I am sure that in out there, there is a good ICO that can we use for the investment because they can give a good progress and they are really serious with their project.
yes, in the end it is very difficult to differentiate a scam ICO or not. sometimes many ICOs have good concepts, but money makes them blind so they only target money. well, but if they think that the ICO can make them get a big profit, of course they will work on the ICO. well, it all depends on the seriousness of their team. in investment matters, of course "DYOR" will always be mentioned.
