According to recent recearch, 56% of 2017 ICOs fail. And you know what? That's OK. 90% of startups fail but the rest grow so high that they compensate venture investors 90% loss and provide very high profits.
So the basic rules with ICOs are very simple:
1. Do the research before you invest
2. Diversify, diversify, diversify
3. Ignore news and HODL
I though 90% ICOs of 2017 failed or failing. Only some good ico with honest team and real products such as: Civic, EOS... most remain ICOs just now building their protocols, hire team etc. We should call that just a paper ideas projects and I can't believe on them.
