Investment in new coins is not risky but people make it risky by not making exploration about it and accept it without any Inquiry. There are a large number of individuals who face success for most of the time by investing in new projects but they don't invest randomly but they utilize their energy to study deeply about new projects, about their team and goals.
We should not accept any coin in its pumping phase because we don't know how long it will be higher and in most of the situations these pumping coins remain lower in price forever and investors become tired of holding it as it possesses no value and also it does not show any growth. So better will be it if you either hold new coins after inquiring or become totally dependent on top and basic coins which will never turn into a scam project.
