Crypto, DeFi, Web3, Blockchain, Smart Contracts, Wallets, Gas Fees, Private Keys, Consensus Mechanisms, Liquidity Pools, all these junky words move your users away. They create unnecessary barriers between people and the financial services they need.
When my friend needs to pay me back for lunch, they don't care about the "revolutionary technology" behind PIX. They just want their money to go from point A to point B without a headache.
The crypto world is basically saying "learn our weird language or you can't sit with us." It's like those exclusive clubs with secret handshakes that nobody actually wants to join. No wonder most people aren't rushing to use these apps!
Web3 shouldn't be a barrier but about building blocks. We should be able to snap these financial tools together without needing a PhD in cryptography first.
I once tried to get my mom to send me some Bitcoin while I was traveling. It was a disaster. I told her to use my old notebook where my Electrum wallet was stored offline. First, she needed to turn on the notebook. Then login to the wallet. Then she had to download Blue Wallet on her phone and import the extended pub key to see the funds. Then click on send, select the amount, and scan the QR code from the offline notebook. After that, she needed to sign the transaction, grab a pendrive, transfer the signed transaction to it, and finally broadcast it.
She gave up after 5 minutes and just sent me money through the bank… which took three days and cost $15 in fees.
That's when it hit me: if my mom can't use it, it's not ready for the world.
This should be the real benchmark for crypto apps, not approval from crypto Twitter or praise from blockchain developers. Can someone who has zero interest in the technology still benefit from it? That's the only question that matters.
Remember when touchscreens were cutting-edge technology? Now toddlers swipe phones before they can talk. QR codes went from weird marketing tricks to how millions of Brazilians pay for everything with PIX every day.
The most successful technologies don't stay visible, they fade into the background. They become so natural that we forget they're even there.
When someone needs to send money, especially across borders, here's what they care about:
The most successful technologies don't stay visible, they fade into the background. They become so natural that we forget they're even there
- Will it arrive quickly?
- How much will it cost me?
- Is it safe?
- Do I need to fill out a bunch of forms?
- Will the recipient actually be able to use the money?
Notice how "is it using a decentralized consensus mechanism?" isn't on that list. Because normal people don't care. And they shouldn't have to
In Latin America, we have amazing regional payment systems like PIX in Brazil and SPEI in Mexico. They're fast and convenient, but only within their own countries. Try sending money between them and suddenly you're back to high fees, long waits, and endless questions about "the purpose of your transaction"
This isn't just annoying, it has real consequences. It means small businesses can't easily expand across borders. It means families pay ridiculous fees to support relatives in other countries. It means opportunities are limited by geography
Imagine an app where you:
- Enter a phone number
- Enter an amount
- Press send
That's it. Money arrives in seconds. The recipient gets their local currency. No one asks what it's for. No one pays more than 1% in fees. No one needs to understand what's happening behind the scenes
This isn't science fiction, the technology exists today. It's just hidden behind unnecessary complexity
To my fellow young developers: let's be the generation that builds technology that solves real problems instead of creating new ones. Let's focus on making things that work for everyone, not just the few tech bros
The builders who will win aren't the ones who can explain the most complex blockchain concepts. They're the ones who can hide that complexity entirely while delivering real benefits to real people
I predict that within 5 years, the most successful "crypto" apps won't mention crypto at all. They'll just be the apps that send money faster, cheaper, and more reliably than anything else
And that's how we'll know the technology has truly succeeded, not when everyone is talking about it, but when no one needs to
The best tech is invisible tech
