It's still worth it, there are people who never stops on investing in ICO's because there's a big money on it. You should know that there are some ICO's who aren't worth to invest and there are some who has big potential so investors are focused to those projects. While investing into those projects and coin don't stop saving.
You should pick a good project in investing in ICO. we all know that many ICO's are just a scam so be very suspisious in investing on ICO's. you should look on the team and the project. If you think it was possible and have a chance to succeed then you may invest on it. My number suggestion was investing in CENTRA ICO.
You had to look and do a research with those ICOs. Make sure that they are transparent, they have real people behind their project. Also there are projects that they have people from other successful projects/coins. And those type of projects can be also a good place to invest your money. Don't just save your money but if it is your bitcoin to save, much better.
Knowledge is there, you can't even invest in any ICO if you don't have this. You have to know what you are doing because if you don't, it's like you are donating your money on those projects without thinking that the people are legit for that project and they won't be scamming you.
