Mining
Also known as: crypto mining, proof-of-work mining
Using computing power to validate proof-of-work transactions in exchange for block rewards, generally taxed as revenue income on receipt.
Definition
Mining secures proof-of-work chains like Bitcoin by solving cryptographic puzzles, with successful miners earning newly issued coins and transaction fees. Mining rewards are generally revenue income at their rand value when received, and that value becomes the base cost for any later disposal. Running mining as a business allows related costs — electricity, hardware depreciation — to be deducted against the income.
Example
Your rig earns mined coins worth R4,000 in a month; that R4,000 is income, against which you may deduct electricity and equipment costs.
Jurisdiction notes
