Shells, Coins, Paper, Code: If Crypto Had a Passport
I think most of us played “shop” as kids and paid with leaves from the nearest tree. A big green leaf bought you a handful of sand cake, and nobody questioned the exchange rate. Looking back, it was my very first lesson in what money really is: something everyone agrees has value.
Grown-up money works on the same idea and has always done three jobs: helping people trade, store value and figure out what things cost. The jobs never changed, but the form did, and according to PBS NOVA, the journey looked roughly like this:
🐄 Barter and cattle, the oldest forms of exchange (try fitting a cow in your wallet)
🐚 1200 BC: cowrie shells, the longest-used currency in history
🪙 1000 BC: the first metal money in China
💵 806 AD: the first paper banknotes, also in China
💳 20th century: electronic money and cards
So in a few thousand years, we went from leaves and shells to tapping a phone at the checkout.
The latest stop on this route, at least for now, is cryptocurrency. I’ve been around crypto long enough to see plenty of new ideas come and go, but I haven’t seen anything newer take its place yet. What I like most is how differently it works from the money I grew up with:
🔹 no central bank behind it
🔹 transfers work 24/7 and across borders
🔹 supply rules are written in code, so nobody can print more on a whim
The choice, though, is a bit overwhelming. CoinGecko tracks around 17,900 coins, and tens of millions of tokens have been created in total, which is a lot more than the number of trees I could raid as a kid. 🍃
While scrolling through that list one evening, an idea hit me. Each fintech coin does its own job in finance, much like national currencies play different roles in the world economy. So which currency would each coin be?

Just so we’re clear, these comparisons are entirely my own and meant for fun, so please don’t take them too seriously.
🇺🇸 Ripple (XRP) → US Dollar
The dollar is the world’s go-to bridge currency, the one others pass through on their way somewhere else. XRP was designed for the same role: a bridge for international settlements between different currencies. Same job, smaller passport.
🇪🇺 WhiteBIT Coin (WBT) → Euro
The euro is one currency shared by many countries, and WBT works in a similar way as the infrastructure coin of the W Group ecosystem, connecting the exchange, Whitepay, Whitechain, and more. The difference I’d point out is supply: WBT is capped at 400 million coins, and regular burns keep reducing it.
🇲🇽 Stellar (XLM) → Mexican Peso
The peso is one of the most popular remittance currencies, with families sending money home across borders every day. Stellar was built for exactly that kind of task: fast, low-cost transfers between countries. I’d call them natural travel buddies.
🇸🇬 XDC Network (XDC) → Singapore Dollar
Singapore is one of the world’s busiest trade hubs, where goods and deals from half the planet meet. The XDC Network plays a similar part on-chain, supporting trade finance and settlements in international trade.
🇨🇭 Ondo (ONDO) → Swiss Franc
The franc is where people go when markets get nervous and they want something calm. The Ondo project brings that same mood to crypto by tokenizing conservative assets like US Treasuries. Probably the most serious pair on my list.
🇭🇰 Quant (QNT) → Hong Kong Dollar
Hong Kong has long connected China with global markets, acting as a gateway between two systems. Quant does something similar by linking banking systems with different blockchains, so they can talk to each other.
Looking at this list, I notice the same thing every time: no single coin tries to do everything, just like no single currency runs the whole world economy. And if money went from leaves and shells to code in a few thousand years, I find it hard to believe crypto is the final stop. My personal guess is that the next form will be built for AI agents paying each other while we sleep.
Then again, maybe Elon Musk is right and none of this will matter. In a July 2026 interview with The Economist, he said money won’t matter by 2036, because robots and AI will produce more than people can consume.
I’m not ready to give up my wallet just yet, but I’m curious what you think: will new kinds of money appear, or will money fade out altogether? 👇
