Are ICO's a good investment?

I've been sharing here in this platform some of my experiences as a new investor in the cryptocurrencies world. Trading, mining and posting on steemit seem to me (up until now) the best ways in which I can make my still modest investments grow.

However I'm now focusing my attention in trying to learn more about this other type of investment: ICOs.

I know that ICOs are a way of crowdfunding accomplished by issuing a new kind of coin or token. That coin may have some purpose on it's own or it could simply serve as a token representing a "share" in the project.

And I have also noticed how many of these have given amazing returns to their investors, just as much as I've seen many scams in the form of ICO's have come to light.

I have found so much information out there about many active ICO's that I've been wondering how to filter it. What should be considered a good source of information about this? I know that some of the people that have earned my respect in this world can give some valuable info about it every now and then and I know that nobody is going to make the work for me in terms of reading about every interesting project's white paper and road map. That's my homework.

But I would like to know about some sites that can give me information about new, current and past ICOs. Preferably, after having left out some of the most faulty projects.

What do you know about this? Have you invested already in your first ICO
