We spend a lot of time talking about making crypto easier to use with better UI/UX, but security still seems like the elephant in the room. Hacks, compromised keys, smart-contract exploits, hardware-wallet issues. Eventually people have to ask whether self-custody is actually as safe as we make it sound.

And then there's the quantum problem.

It's believed that a sufficiently powerful quantum computer could eventually threaten the public-key cryptography used by many blockchains. That doesn't mean Bitcoin or Ethereum are getting hacked tomorrow, but migrating an entire ecosystem to post-quantum cryptography could take years.

So what should the industry prioritize now, better wallet security, quantum-resistant signatures, easier migration between cryptographic systems, or something completely different?

Curious what security approach you actually trust.

If a company wants to put an actual business process onchain, they don't just need a blockchain. They might need payments, tokenization, identity, compliance, custody, storage, privacy, cross-chain messaging, etc. And then they have to figure out which provider to use for each one, negotiate with them, integrate everything, make the systems talk to each other, and somehow keep the whole thing compliant.

At that point, are we really making Web3 infrastructure simpler?

It feels like the industry has spent years building really good individual components, but not enough effort making those components work together as one usable system.

The interesting question to me is whether the next phase of Web3 infrastructure is less about building another primitive and more about composing existing primitives into complete, verifiable workflows.

I've mostly seen quantum computing discussed as a threat to crypto, but there's another side to it that I find interesting.

If quantum technology eventually becomes practical, it could potentially improve things like optimization, simulations, cryptography research, and other areas that could benefit the broader blockchain ecosystem. Faster or more sophisticated computation could even create new possibilities we haven't considered yet.

The obvious problem is that the same technological breakthrough could also challenge some of the cryptography that today's blockchains depend on.

So I'm wondering where people stand on this. Should crypto see quantum computing primarily as a threat that needs to be defended against, or as an opportunity where the industry should start adapting early?

And are there any projects actually experimenting with quantum-resistant infrastructure in a meaningful way, rather than just adding it to their roadmap?

The narrative is one of those I'm watching for the next rally and the reason is pretty straightforward.

Bitcoin is by far the largest crypto asset, yet only a tiny percentage of it is actually being used in DeFi. If native BTC can become usable for staking, lending, and collateral without introducing unacceptable custody or bridge risk, the addressable market is enormous.

But there is also a problem, and that's the fact that a lot of the early BTCFi growth was built around wrappers, bridges, and yield products. That works until you start asking whether an institution holding billions in BTC actually wants those additional trust assumptions.

We've seen the sector grow quickly, but we've also seen TVL contract sharply when incentives disappear or risk becomes clearer. So I'm less interested in headline TVL and more interested in whether BTCFi can develop sustainable credit markets around BTC itself. If that happens, I think the narrative has legs, if not, it probably remains another cycle where the idea was bigger than the actual usage.

What do you think will happen with this narrative in the future?

Everyone talks about AI agents themselves, but I think the bigger opportunity might be the infrastructure underneath them.

If AI agents are going to handle payments, move assets, coordinate tasks, and interact with businesses, they'll need things like:

• payment rails
• wallets
• identity
• orchestration
• verification
• compliance
• cross-chain execution

The flashy agent apps get most of the attention, but history usually rewards the picks-and-shovels layer.

Which crypto projects do you think are building the most important infrastructure for the agent economy, and why?

People always say "never sell your Bitcoin," but I rarely see them actually using BTC as collateral instead. Example is Saylor.

Is it because the infrastructure still isn't there, or do most holders simply not trust it yet?
