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
Unless it's "the" project, I wouldn't participate in an ICO. The prices have been plummeting as soon as the coins hit the market. Research the project you like, wait for it to hit the exchange, get it discounted from ICO price.
to invest I further recommend for Bitcoin because Bitcoin is a suitable coin to invest because with prices that continue to develop can make Bitcoin as a mainstay in running a business on the market. for Altcoin itself is more suitable to run trading in order to become a coin that is so profitable in the future.
