In my opinion now better buy and HODL TOP 20 coins. Not buy temporarily ICO tokens, because them price very strong less after ICO.
If you have got better mindset for ICOs and you think this is better for you than trading and investing in some coin, go for it. We all are here to advice you what we learn from the market and what we learn from experts. But that is not necessary for you to listen to us. We may be wrong in your case and this ICO system can be profitable in your case. So research by yourself.
