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?
Knowing that success rate of ICO nowadays is decreasing I am not investing in ICO for now. I preferred to invest in existing projects which altcoins are already listed in exchanges.
