Do I need to search for a potential ico project to invest in?
Yes ofcouse . If you don't search for the best you would not be able to get the best results out of it .
Let me help you out here , I would suggest you to invest in the project called
REMME . It is a very futuristic project with a very practical and realistic take on all the security problems by password free interfaces . No one ever thought about such amazing solution . So i highly recommend you to invest on that and it is also registered already .
