There will be advantages and disadvantages of course. First hand, with regulations, danger of using bitcoin in the black market will be mitigated, danger of money laundering through the use of bitcoin will also be avoided, trust of people to the matter will be increased as will as security but for others, too much of these and that are very unlikable. It will be a hassle for them to abide by those regulations so those who don't want it will not go into it.
I dont think regulations really is a AML issue, I think it is more to control a new monetary market from a government perspective, which is understandable of course, no matter ones opinion
I agree, though money laundering might be one of the many reasons, but It wasnt the primary one.
Cryptocurrency like Bitcoin is a threat to the current banking system, and It is ironic to think that the banks has more laundered money than the whole cryptocurrency market cap.
