Sometimes it is a good thing to invest in ICO sometimes it is not. Well basically if the team is good, the product has a future then you may take a risk to invest into that ICO. You must understand that you are not investing into a firm product but into an idea. Sometimes it works out well sometimes it doesnt. Right now the release of ICO dates is also critical. If the release date is somewhere near a btc fork, then you might want to keep your money in btc as you can buy cheaper later as people tend to dump their tokens. You can also acquire cheaper tokens when the bounty is distributed where the bounty hunters go for their quick buck. It totally depends. I would say wait for the product release, then evaluate the product then invest. Or if you like some risk, do invest a little in the ico. If it works for you then get some more when it dumps.
