For Australia but probably similar to other countries…:
Example:
If I bought $1000 in BTC and swap this for USDT with a value of $1500 a year later, this a taxable event and there is a $500 realised gain.
However do I have to pay tax on this for this same calendar year while I still hold USDT in my wallet. Or could I delay paying tax on it by selling the USDT for fiat a year later?
Thanks!
