Last week, the Bank of Ghana announced a 5% fee on dollar cash withdrawals from dollar bank accounts. Some banks have even stopped allowing dollar cash withdrawals altogether. This is a massive blow for both businesses and regular people. Let me break down why in a few simple points. And then show how I use stablecoins to protect myself from problems like this.
The Ghana Cedi trades like a shitcoin. Over the past two years it's swung from 11 to the dollar, up to 16, back to 10 and now it's sitting around 12. Beause of that volatility, many businesses and people prefer to hold dollars and transact in dollar terms.
The Bank of Ghana set an official dollar-cedi exchange rate that's much worse than the street rate. So if you withdraw cedis from your dollar account, you get far less than what your dollars are actually worth on the open market.
Paying with a card isnโt much better. You still get hit with the bad rate. And thatโs if the payment even goes through. Lots of cases where dollar card payments fail because a bank is โlow on dollars.โ
This announcement is just the latest reason Iโll never use a Ghanaian bank, or any bank in this region. At home, I bank myself with stablecoins.
I keep USDC in my self-custody wallet. When I need to spend, I swap stables for cedis straight into my mobile money account at the real street rate, which is far better than what the banks give.
The value is simple: I control my money. I can spend it whenever and however I want, on fair terms. Thatโs how it should be.
(For context: mobile money is basically digital cash tied to your SIM cardโitโs what everyone here uses. I used to cash out with Binance P2P, but these days I use Accrue)

I often get asked the question, "What's happening onchain?"
The answer usually lies in incentives. Every new wave of onchain activity is driven by a new incentives playbook. For example ๐
[2020] Liquidity mining
- Compound, a lending protocol, kicked off the liquidity mining trend in June 2020 with a wildly successful token incentive program. Compound's TVL spikes from $100M to $600M in one week
- Every DeFi protocol under the sun copied this playbook and DeFi summer entered full swing.
[2021] Joint Liquidity Mining
In early 2021, the Polygon Foundation launched joint liquidity mining programs with popular DeFi protocols.
First was Aave. Polygon gave $40M worth of MATIC to lenders and borrowers on Polygon Aave. Users bridged to use Polygon Aave to earn these incentives -> Polygon Aave's TVL grew rapidly.
Polygon repeated this playbook with other protocols like Curve and Sushiswap. Polygonโs TVL jumped from ~$100M to high billions within two months.
The playbook was replicated by a host of other chains like Avalanche (see Avalanche rush) and this drove the alt-L1 rotation in 2021.
Learning crypto data science changed my life and was 100% free.
If you're looking for a change (I was a transport planner), start coding 1 hour a night. More on weekends.
Pick a simple @DuneAnalytics project. Learn just enough to build it. Pick a bigger project. Repeat.
It took me 3 years to get to my current level of crypto data proficiency (preceded by 3 years of writing coding in other fields). Here are some free resources you can use to get there 10X faster ๐
1. SQL and Blockchain data

How to become a DeFi frontend engineer (starting from scratch):
Step 0: Learn basic JavaScript and HTML from a free resource of your choice (CodeAcademy, w3schools, freecodecamp .etc)
For JavaScript, if you understand variables, functions, if statements, and while loops then you're fine.
Step 1: Work through the reading and exercises in the 'Get Started' section of the React documentation (Quick start, Tic-tac-toe, Thinking in React .etc)
React is the most popular library for frontend engineering
