Say I have two bitcoin in my wallet, bought at different times (let’s call them BTC1 and BTC2 with BTC1 being the one bought first).
Now I transfer one coin to another wallet (I guess this is BTC1 due to Fifo rules).
Now I transfer the coin back to the initial wallet, so the initial wallet has two coins again.
Now I sell one coin.
For tax purposes (and how does accointing handle this): Which one did I sell? BTC1 or BTC2? I.e., was BTC1 “appended” when swapping it back from the other wallet or stayed BTC1 the first, as it was the first when I bought it?
I.e., more generally: Can I reverse the fifo order of coins by swapping them between wallets? How is this handled in Accointing?
