> What are the tax implications of playing with Bitcoins? In the US, presumably? It's ever-so-slightly different from other investments. AFAIK it's a real grey area regarding mining. If you mined the coins, maybe those were taxable income then (offset by big capital expenses?), at the market value at that time. I think that's where the differences might end. Now that you have them, plain old capital gains tax likely applies. > how will the IRS ever find out? ... What if you just keep the gains and keep quiet? You end up accepting some risk that you don't end up being investigated. Very much of the taxes that you pay that are not part of withholding operate this way. Be honest and have nothing to fear or risk an audit.
