Have you heard of ICOs with multiple rounds? Like they raise a certain amount of money now, use that money for primary aims and goals, and then a few months/years down the line (as part of their original plan) launch a second round to fund additional goals and further project development? Just wondering if this is a thing, if so please provide me with some links to projects that have done so.
I have not heard about new projects that conduct similar ICOs. This is of course an interesting idea, but I think that if the developers raised the money necessary for the implementation of the project, they will be able to realize it without additional investments.
Unless they need money to advertise a finished project. However, if the project is good, then finding additional funding for them will not be a problem.
