Crypto Mining in South Africa
South African crypto mining lives or dies on three things: the rand-per-kWh you actually pay, the efficiency of the hardware on your DB board, and the resale liquidity of the unit when you exit. Everything else is noise. This hub pulls together the playbooks we use at our Bedfordview office every week, from first-time S19 buyers to operators running hosted hashrates and bespoke kit-outs. Right now our SA stock leans hard on the latest-generation efficiency leaders like the Bitmain Antminer S21 XP 270TH on Bitcoin, the Bitmain Antminer L9 17G on Scrypt, and the Bitmain Antminer Z15 Pro 840k for Equihash.

What Our Customers Have To Say
Frequently Asked Questions (FAQ)
On pure Eskom residential at R2.80 per kWh, a new S21+ 235Th runs at roughly minus R2 100 per month. On hybrid solar (10 to 12 hours of daytime PV with grid for nights) at a blended R1.50 per kWh, the same unit returns roughly R1 500 per month. Full off-grid solar at R0.80 per kWh amortised drops the effective tariff and pushes monthly net to around R3 480. Solar capex itself is excluded from those figures and adds R150 000 to R280 000 to the upfront bill. Run the maths against your real municipal invoice before committing. For the most accurate scenario today, run the maths against the Bitmain Antminer S21 Pro 245TH or the solar-friendly Avalon Q 90T rather than the older S21+.
Yes. Mining itself is unregulated. The income is taxable. SARS treats mined Bitcoin as gross income at the rand value on receipt, with capital gains tax on later appreciation when you sell. Importing ASIC hardware might require special permits. A reseller with a valid VAT number handles those requirements for you.
Not strictly, but on Eskom residential alone the cashflow is negative for every current Bitcoin ASIC. Hybrid solar is the practical break-even point. Full off-grid is the scenario where mining becomes a real monthly business. The third option is to treat mining as a Bitcoin accumulator and accept negative monthly cashflow in exchange for stacking BTC at a known rand cost.
If your capex is under R20 000, used is the only sensible answer. A working S19 100Th at R10 000 has the lowest rand-per-TH on the market. If you have R75 000 free and stable hybrid or off-grid power, a new S21+ 235Th pays back faster on hybrid solar and holds resale value better. New S19K Pro 120Th at R19 500 sits in the middle, full warranty, modest ambitions.
