I sell about $1400 in Bitcoin that I mined myself to Coinbase.com. They transfer their exchange rate, which is about a tenth less than the Mt Gox rate, to my American bank account. They are honest about that, but then a few weeks later I get all these letters in the mail demanding payments for some credit card debts from 20 years ago that were supposed to have been written off, with 500% interest. thanks alot San Francisco people. now I'm waiting on the IRS, dammit.
