When deciding in which coin to invest you can either blindly follow suggestions by others or make your own informed descision based on some criteria:
- What problem does the project attempt to solve?
- Is it a solution looking for a problem?
- Is there active development behind the project? (check Github activity)
- Has the team produced anything but a whitepaper?
- Are there established competitors which are much further into delivering a working product?
- Cross reference developers against previous scam projects
- Current market capitalization of the coin
This is a great list of things to consider before investing. It's true that there's a lot of ICO going on each month, and it's really hard to rely on the information that most people here would give. It's better if you would study and examine the ICO and the team behind it carefully because it's your investment, you shouldn't rely on others when it comes to investment.
