When investing in ICOs, are there times when you invest for a high ROI but don't really care for the cause behind the project? Or do you only invest when you believe the project has a strong use case and feel personally attached?

I am new to BitcoinTalk but I am not new to investing. With all my investments, my criteria is whether I believe in the idea and whether it is something the world needs. In other words, if I don't feel personally invested in the idea, then I won't be investing my money.

For example, there is a new project called Protex and I invested in their pre-sale because I believe they are going to solve a major issue the entire world has. They are a data security company that will give the power of data back to the users instead of large corporations. All while essentially eliminate data breaches. With a platform that will positively affect everyday of my life, it is easy to be invested in them.

But I want to know your thoughts! In it just for the money?
