How do you calculate taxes on alt-coins bought and sold with Bitcoin? For example if i bought 10 bitcoins worth of Monero, and monero rose 10% and i decides to sell for that extra bitcoin, how does that become taxed? Furthermore if/when i decide to sell the 11 bitcoin i now have for fiat, how might that be taxed? Thank you in advance.
you need to consult a professional my friend, any suggestion here may be worse than doing nothing for you.
but as far as i can tell you, i believe you report taxes on the profit you make from trading and if you calculate it after some time not each trade. so for example you make 20% and lose 10% and make 5% then you report total of 15% profit and pay taxes on that.
but also at the same time i think in countries like US they consider bitcoin a commodity so maybe having bitcoin may be subjected to taxes. again as i said consult a professional lawyer or something.
This is the best suggestion here in my opinion, even if altcoin is not taxed, you still need to declare your profit to the government. Especially if your government is very strict when it comes to tax implementation.
