One thing I notice when looking at the cryptocurrency industry is that there are actually numerous billion-dollar business opportunities just waiting to be tapped. But many people haven't realized this. Today, I want to share five business ideas I've been paying close attention to for years. If any of these can be realized, they could become quite huge.

The first idea that comes to mind is the concept of OneKYC. KYC verification is the process where users confirm their identity, but this is one of the most tedious parts of the crypto industry. Every time you use a new exchange or app, you have to upload documents, take a selfie, and wait for approval. Doing this repeatedly is really exhausting.

So, what if there was a portal where you could complete a single KYC verification and then access multiple platforms? Users would finish their OneKYC verification and then just click on supported apps to start using them immediately. On the backend, the platform would send the verified KYC information to partner platforms in a compliant manner, and accounts could be opened simultaneously. Revenue models could include referral fees or charges based on the number of verified users. Crypto apps struggle most with high customer acquisition costs and user drop-off during KYC steps, so a platform that can directly provide already-verified users would hold significant value.

Next is the idea of an automated peer-to-peer exchange. Traditional P2P trading is slow, cumbersome, and fees can reach 5–10%. Traders chat in windows, manually coordinate with each other, and wait for seller confirmation. This can take hours and carries fraud risks. However, using zero-knowledge technology, the platform could verify fund transfers automatically while protecting both parties' privacy. Once payment is completed, the system would automatically confirm and release the crypto assets into the account within 1–2 minutes. Interestingly, this could become a deposit/withdrawal channel that doesn't require KYC verification. Users who want to use Cash App or PayPal have already verified their identities on those platforms, so this setup could attract legitimate users while deterring scammers. One platform achieved about $20 million in trading volume in its first year. If executed properly, it could grow into an app with over $100 million in users.

Issuing cards for AI agents is another very intriguing idea. In a few years, AI agents will handle payments across various industries. Unlike typical card issuance projects, this would require designing specific restrictions so AI can spend funds appropriately—such as limiting purchases to certain stores based on tasks, setting strict budget caps, and implementing strong security measures. In the future, thousands of companies will develop AI agents, most of which will need payment modules. Providing such payment solutions could grow to the scale of Stripe. It might start slowly but then suddenly explode into a major business.

The fourth idea is a trading marketplace for crypto companies. Over the past year, the industry’s trend has shifted from speculative concepts and meme coins to real businesses—new banks, international remittance, digital wallets, DeFi protocols… These are companies that are actually profitable. However, buying and selling these companies is mostly done privately. Buyers contact sellers via direct messages, and sellers reach out to potential buyers one by one. There’s no open, organized marketplace for trading native crypto companies. SaaS platforms like Acquired have been hugely successful in this space, but there’s no crypto-native equivalent yet. A trust-based, verified marketplace would allow investors to systematically find good deals. Acquired earned over $7 million in order-matching transactions in 2025, charging both buyers and sellers. Selling a company worth $1 million could generate around $100k in revenue. A platform that becomes the default exit route for crypto companies would be a winner in this field.

The final idea is providing loans to crypto companies. This is a high barrier but targets founders of emerging banks who already understand compliance and risk management. Over the past year, crypto banks for retail users have emerged, along with corporate crypto banking. But the real opportunity isn’t just account opening—it’s lending. Crypto companies find it hard to get traditional bank loans and mostly rely on venture capital. Meanwhile, platforms like Shopify can connect businesses with fintech lenders that offer revenue-based financing. Nobody has really done this in the crypto world yet. Many lenders are offering funds at 15% annual interest, and if you lend at 25–30%, you can earn a spread. Of course, strict risk management and complex compliance are necessary, but the industry is maturing, and stable, profitable companies are emerging.

In conclusion, the ideas themselves are not valuable; what matters is how you execute them. But all five of these ideas, if successfully implemented, have the potential to become billion-dollar businesses.
