We would have a big problem since bitcoin legal would mean be exposed, and some bad people will find your adress and visit your family, this is what i believe would happen with bitcoin legal. The good think is it would bring more and new fresh fiat investment, that should affect the bitcoin value in the short period if not instant.
I really don't see it this way. That's true that it is a bit of a problem if it becomes legal. But it's not about bad people visiting your house just because you own bitcoin and how will they find you. What might visit you is your government, checking your assets and correcting your tax declarations. But no bad guys will visit you, that's for sure. What bothers me when it become legal is the regulation. That means no more extra tax free money.
