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?
one suggestion from me, don't jump to conclusions when the first one fails. Your first failure might be because you were less thorough and only interested in a large buyback,
do not easily believe the big results that will be obtained, you should first read the whitepaper carefully, and see if the peoples involved in the ICO project are real.
Some Whitepapers are misleading. We cannot really tell for sure. Sometimes the team might be real but have ulterior motives. You are right though "never believe in big rewards", one has to be really meticulous
