It's a law enforcement issue, not a currency issue.
Anything that can be done with a suitcase full of cash can be done with bitcoin. Laws already exist to deal with financial crime.
Can you send a suitcase full of cash to the other side of the world in less than a minute? It's a law enforcement issue
and a currency issue.
The invention of the wheel made it much faster to cart gold around too.
That's not the point of my post. You're argument is that nothing needs to change, but just as currency has evolved laws will evolve. It's one thing to want everything to stay the same, but it's another thing to be realistic and realize legislation is coming. Too much money is changing hands for the power heads not to want a cut of it. Too much money is also being spent "illegally" for them to turn a blind eye to it. The fact legislation is coming makes it a currency issue.
