I'm thinking because they are Reverse ICO (like they did not host any ICOs until now but already have a business that's running) they should be less risky.
What do you guys think??
correct, they are
less risky but not safe. in other words these ICOs are still very very risky and it doesn't matter if there is some real business behind them. if their business was so successful then they wouldn't be needing to raise funds like this through an ICO.
you should ask yourself this: what does this new token offer the world that they couldn't do it without it?!! the answer is nothing in all ICO token cases that have been created so far in the past couple of years.
