Do you have any warrantees that coin won't be dumped when it reaches exchanges?
Well if you expect that someone will give you that kind of warranty, then you are in a dreamworld. It is just speculation and probability based on the project, business model and market condition.
If they can warranty that I will sell my house to invest into this ICO. they will have some plan to protect price like send bounty reward after 1-2 month. but they cant warranty
