I travelled from Nigeria to Cotonou for Bitcoin Mastermind 2026 with three problems waiting for me the moment I arrived. I'm an English speaker in a French‑speaking country. I had no CFA on me. And outside my Nigerian crew, I had no real‑life friends there.
The language problem I mostly solved with Google Translate. The friends problem solved itself, because there was a Bitcoin community waiting and I connected with French‑speaking Bitcoiners fast. But the money problem was the real one. I had no local currency. What I did have was sats.
Why cash is the hard part of travelling as a Bitcoiner
If you've moved around West Africa with Bitcoin, you know the usual offramp is another person. You find a Bitcoiner, you trade sats for cash, done. That works when you're standing next to the community. It falls apart when you're not.
None of us Nigerians could just walk into a bank and withdraw. We didn't have local accounts. And I couldn't always guarantee I'd be in the same room as someone willing to trade. So the question became simple: how do I turn sats into CFA without depending on finding the right person at the right time?
What Flash did for me
Flash is a Bitcoin platform built for West Africa. It lets you buy, send, and pay with Bitcoin over the Lightning Network, and it runs on the mobile money rails people here already use, including MTN Mobile Money, Moov Money, Togocel, and Celtiis. It's live in Benin, Togo, Burkina Faso, and Côte d'Ivoire, with Niger on the way, and you can start from as little as 100 FCFA.
For me the important part was the offramp. Flash let me convert my sats to local currency without needing another Bitcoiner physically present to trade with. That single thing changed the trip.
Through Flash we paid for Uber rides and covered day‑to‑day costs directly. Instead of rationing a fixed amount of cash I never had in the first place, I could offramp what I needed, when I needed it, from the Bitcoin I was already carrying. Here is a short video I did of me using flash.
The part that surprised me
The app is in French. I don't speak French. I still navigated it and completed payments without knowing what half the labels said. That tells you more about the product than any feature list would. If a tool is simple enough to use blind, in a language you don't read, under travel pressure, the design is doing its job.
The interface was seamless and the flow was obvious enough to follow on instinct.
Who should use it
If you're travelling to Benin, Togo, Burkina Faso, or Côte d'Ivoire and you're carrying Bitcoin instead of local cash, this is a genuinely useful tool to have before you land. It runs on mobile money, so it meets the local economy where it already is, and it removes the dependency on finding a P2P counterparty even when you're outside the Bitcoin community bubble.
Shout out to the builders. This is the kind of practical infrastructure that makes Bitcoin usable for real life in West Africa, not just conference talk. You can check it out at bitcoinflash.xyz
