Let's Bitcoin takes off. Say you lived in the US and had an online service that dealt in the equivalent of ~20,000 USD or more income for you (personally). What are the laws for income tax on a currency like this? Can you get in trouble with the IRS by simply having tons of BTC that the market values at (currently) almost 5$ per BTC?
I think they can take taxes from Bitcoin using exchanges, we pay for fees so maybe all exchanges takes a little bit of that to just pay for the taxes we take.
