There are so many New ICO's these day ? Is that safe to invest in ICO ? any 1 invested in 2018 ? 2017 was the year of ICO's but is that still safe to invest ? or how to know which ICO is good to invest ? like GIG9, Eligma, Medicalchain, Trustedthealth
well if the ICO that you are going to invest to has a good developer team, you can try to invest there. but i think it is safer to invest in the mainstream coins like btc and eth since it is supported by so many investors.
