ICOs are a great way to maximize profits because you can get the coins early, at a low price. But it is very important to choose the right one as there are many. Some regulation would not harm - no bans but some audit before an ICO. Something similar to QSP.
Before investing you need to do your own research and choose wisely. There are many websites that do ICO ratings, but you should take their ratings with a pinch of salt - it is always possible to "buy" a good rating.
If you are interested in investing, take a look at HOQU, it is very highly rated and will release the app in March:
