I have a question though. If you lost 10,000 on a trade, but then, a month or 2 later, you earned 12,000 USD off trading, would these amounts cancel each other out (so, it'll be 2,000 profit), or would you need to report taxes for each of the transactions? I'd much prefer just reporting the total gains over a year, instead of each little transaction.
However, what would the IRS say if I have bitcoin to trade to an altcoin and earn profit in bitcoin? Is that taxable?
...
They would say you have a gain and need to report it as taxable income. And depending on the amounts involved you may need to file and make quarterly estimated payments.
Most of the retailers investing and trading crypto don't have much experience with tax forms and whatnot. This is their first experience with anything related to investments in general. It only makes sense to be a little more lenient here as tax agency. People trying to do the 'good' thing by reporting their gains shouldn't be penalized but helped to correct wrong declarations.
I have zero respect for any tax agency. They expect you to fill their pockets but don't do anything to help you where possible. Get lost you swine!
