There is no such a thing, nobody can tell the future, what you can do is some research and asses the risk / return of the project. Is bitcoin scam because you know nothing about Satoshi Nakamoto ?
yes that right
bitcoin is difference with ICO. we can check bitcoin code to make sure Satoshi can't do anything to bitcoin network. ICO is difference. We send their our money to get token( which dont have value if they dont do anything). so we need their information to make sure if they want take our money they must pay by blood( for sure)
