SA Pioneering a Payments Revolution
SA’s R1.3 trillion in monthly card payments can be done smarter – and this local player’s making it happen…
When the unknown person (or people) known only by the pseudonym Satoshi Nakamoto published the famous whitepaper called Bitcoin: A Peer-to-Peer Electronic Cash System back in 2008, it launched a $3.79 (R65) trillion industry.
But while most of the 22% of SA who bought crypto likely did so as investment(s), the intention with Bitcoin was actually to replace the cash system. Hence, the genius design:
Solves the “double-spend problem” sans central authority: Before Bitcoin, digital money required a trusted intermediary (bank or PayPal) to prevent fraud.
Creates digital scarcity and predictable monetary policy. Mimicking the scarcity of gold, but with added portability, divisibility and the transparency of software.
Incentivises security through elegant game theory. Bitcoin’s proof-of-work system aligned self-interest with network security.
But even with this great design, Satoshi’s dream of it replacing is a tall order: The network itself can handle around 7 transactions per second. In reality, Visa handles ± 65’000 per second. Bitcoin often falls short of the scale to truly compete globally.

Making it useful for everyday payments
The Lightning Network is Bitcoin’s answer to that problem. Instead of recording every single transaction on the blockchain, it lets users open payment channels, like running tabs, where they can send money back and forth instantly and for almost zero cost. Only the opening and closing balances ever touch the main Bitcoin ledger.
So you can pay for coffee, tip a creator or send money across borders. It’s the layer that could finally make Bitcoin fast enough for the real world, and it scales: in theory, it could manage millions of transactions per second, but that requires more people to use it.
The final frontier?
But just how do you encourage usage? You need to be able to pay with it – everywhere. And that’s what local startup Moneybadger is pioneering.
Founded by one of the co-founders of Luno and an early engineer at Snapscan, Carel van Wyk, Carl Kitzinger and Brent Peterson, Moneybadger enables merchants to get paid in Bitcoin using currently in-place infrastructure such as scan to pay (think Zapper).
We first saw the tech 8 years ago when a video emerged of a Bitcoin payment at Pick'n Pay. Fast forward to today: you can now pay at Pick'n Pays nationwide, Bootlegger Coffee Co., various online stores that use Peach Payments, all 31’000 Zapper-enabled stores, as well as 650’000 Scan to Pay-enabled merchants across SA.
How does it work? Simply look for the “Scan to Pay” feature on your preferred crypto app or download the Moneybadger app next time you pay. It’s that simple, Moneybadger handles the rest.
Merchants can then select to get settled in SA Rands, Bitcoin or stablecoin. Satoshi would hope they choose Bitcoin and keep money in the system. But for that to become the primary option, we probably need to see SARS accepting tax payments in Bitcoin. If that ever happens, it would mark the moment Bitcoin truly completes Satoshi’s vision, a full-circle return to everyday use.
We are watching this space.
WHATSAPP’S HOT
They Built What on WhatsApp?!?
Who still prints programmes and fumbles through event schedules?
For our final Open Letter event of the year — our biggest one yet — we’re taking the entire experience to WhatsApp. From sponsor giveaways and competitions to networking challenges and speaker sessions, every part of the evening lives in chat.
But here’s what’s really clever:
✅ Attendees scan their QR code to get a personalised WhatsApp hub
✅ Full event programme, partner list and competition entries
✅ So each person can get the most out of their experience.
Built by our friends at Chat Inc, this makes WhatsApp the single control centre for 180-something guests and multiple brand activations. Can’t wait.
What would you build WhatsApp today?
Chat Inc proudly sponsors WhatsApp’s Hot
The trusted WhatsApp people powering WhatsApp and Chat Commerce experiences for some of SA's largest and most respected brands, from Lead Acquisition, Outbound Direct Marketing and enterprise-grade transactional chatbot platforms.
Chat Inc started locally, and today it is trusted by brands globally.

IN SHORT
Well, well, lookie here…
🌊 (Sea)horse Power. South African startup SeaH4 just snagged top prize at the ClimateLaunchpad Global Grand Final 2025 in Vienna with their innovative algae-based fuel, pocketing €10,000. Nice.
📈 FirstRand Dives into Optasia. FirstRand is snapping up a 20.1% stake in Dubai-based AI FinTech Optasia, just before its planned listing on the JSE. Interesting.
🍏 An Apple A Day. Apple just passed the whopping $4 trillion market value, hitting an all-time high and joining tech giants Nvidia and Microsoft in this exclusive club. How you like them 4 trillion Apples?
⛽ Pump It Up. South African motorists can breathe a sigh of relief at the pumps next week as a fuel price cut is on the cards. Petrol drops 58 cents per litre, while diesel drops 25 cents. Here’s hoping we get another one for Dezemba as well.

Your 2 cents…
“I’m not aware of any country that could leapfrog industrialisation (aside from countries positioning themselves as tax havens) to achieve sustainable growth. The 30% of unemployed need jobs.”
Indeed, Jan. Not to mention manufacturing often comes with better benefits and packages than the service and tourism sectors. 💪
