I think yes, it will help, because they are more protecting our tokens to hackers, and this is also their assurance that we do not enjoy them, it is often used on ICO's. so it's a big thing in the field of cryptocurrency.
There are no so called protection about hackers. They can breach anything if they wanted to be, they even attacks and defamed *.gov websites, what's more a trading exchange or a ICO project? So there's really the risk that your personal data will be exposed and exploited by them.
I agree that it can bring some air of legitimacy but it will not be the main reason for bitcoin to go mainstream. It boils down as how people used it, whether as currency (what we wanted) or store of value (as investment). So it really cuts both way, somewhat contradictory so for us, we might or might not followed the procedures but as long as we enjoy using bitcoin and crypto then who needs KYC/AML after all?
