I had invested one ICO previously, it failed although I didn't contribute a huge amount on it. A news yesterday made analysis on blockchain ICO projects, mentioning 92% of these ICO projects are failed.. Should I stop investing the others or any really potential ICO suggest?
For a long time I have not trusted ICO because many of them fail, while others are just scammers, so it's better to buy coins that are already on the market and traded.
