You don't have to pay tax when you trade one cryptocurrency for another
Could you share your sources for this please? I've been trying to figure out the same myself, and my understanding was that if swapping BTC for any other asset (Crypto included), then it would be subject to capital gains as per:
Disposing of an assetDisposing of an asset includes:
- selling it
- giving it away as a gift, or transferring it to someone else
- swapping it for something else
