> Until you use/exchange them, you aren't taxed.

As you're not a tax expert and neither am I, take my objection to this with a grain of salt, I think this is wrong though. When you have income from mining, that's income that should be reported at the market value of the coins at the time that they were income (when you received them.) AIUI they are taxed as income, and you should pay taxes for that income based on your regular (marginal) income tax rate. Once you've paid that income tax, you've established what's called a cost basis for capital gains. (This is also what you have when you have bought a coin rather than mining it. This is considered a "taxable event," even if the money you received in the exchange is never withdrawn from the exchange.)

If you buy something using your crypto asset as payment, or if you exchange them for currency, then you might also owe capital gains tax based on the difference between the cost basis, and the price/value you received for your sale. (If the price went down after your cost basis, then instead you have a loss, and so you don't owe capital gains.)

If you bought something, and the price went up between when you mined and when you made the purchase, then in addition to the income tax, and the capital gains, you will _also_ owe sales tax on the purchase, unless the seller collected the sales tax. (Although unless you are running a scheme to systematically undermine sales tax, and they have you with assets which can't be explained any other way I am not sure how they can ever prove that you owe that sales tax.)

When you are paying capital gains, the usual capital gains rules apply. If you have held the asset for longer than a year, you pay the long-term capital gains tax rate which is lower. The rules are (and this is the point where I'm talking way above my pay grade, but I think I've done my homework) first-in first-out, no like-for-like exchanges, which means if you sell some BTC and receive some ETH as payment, those are two taxable events. (The BTC sale is taxed at the capital gains rate for the USD value of BTC, and the ETH asset establishes a new cost basis at the USD price for ETH.)

If you have held the asset for less than a year before it is sold, then you pay the short-term capital gains rate. If you are not paying capital gains, and your aggregate transaction volume for the year on any given (compliant) exchange is above 10 or 20 thousand dollars, then you are very likely to be on their radar.

If you have losses over the whole year, and no corresponding gains to cancel them out fully, then you can take the excess loss against your income for a deduction in income taxes (subtract the taxable value lost from your income).

Please don't take my word for it though, I have someone that does my taxes for $200 or $300 and I use http://bitcoin.tax to extract the data from the exchange and provide them with the data in a form that they won't balk at. But you can take this as some free tax advice from someone who filed and paid their crypto taxes last year (and obv. also took the loss this year!)
