I am a Chinese student in US right now, and my taxation status is Nonresident Alien.
Since IRS has announced bitcoin as "property", I just wonder how to define my gains from my sell of bitcoin in US. My husband bought bitcoin on Chinese website by RMB and I sold them on coinbase to get USD.
According to IRS's explanation, is the money I gained from coinbase "US source property gains"? If so, how to calculate the gains? Does IRS accept transaction records from Chinese websites? Some of the websites even went bankrupt already.
It's my first time to file my taxes in US, I really don't want to cause any trouble. Thanks!
