Ico's investment is very risky because many ico projects are scam, need to be careful in choosing a quality ico project, you need to know the core team and also the ideas of the project.
It actually between us on how we commence into selecting ICO to participate with. I know not all ICO today looks promising as we know that some of them are just a ghost project. We think it is so risky cause we can't be sure if their is profit in the end or not, as the market decide what well happen next either a certain project you have participated with will succeed or not.
