Investing is a high risk way of raising our money so we should be careful in investing especially in ICO, We should never invest anything that we cant completely afford to be gone like a bubble. Investing is just like gambling, we dont know if we will earn some or lose some, but if we do not try,, We will not have a chance of becoming rich.. So invest and invest those amount that you dont need.
Yeah, it is always a huge risk and every investment with the certain risk should always be considered first before even investing which is what a lot of people do not do and always get greedy or emotional. As long as you know it is not all company that would end up successful, then you will also know it is not all projects that would end up successful in the long run.
Nevertheless, this is different from investing in scams, as you would have yourself to blame if that happens, but the important thing is to not expect too much and at the same time expect too much. At the end, never get greedy, diversify to minimize the risk and always know you are investing in a solid project.
