Sometimes yes - sometimes no depends on the project
Nowdays never invest in ICO. too many fake ICos now. in 2017 I invested in many projects, I made much profit but at the end 2017, I lost some money because the project failed of the price is too low, i invested in scl, hazza and rvt and latoken in the end of 2017. All are lost. the projects gave me zero proft because I think they are not transaparant about the token supply in the market. Now I never invest in ICO. I think ICO now , too many scam and dump and pump. Wait for ICO certification , i may back to invest in certified ICO.
