Bitcoin has always been seen as digital gold: scarce, secure, and built to be held. But what happens when Bitcoin starts moving beyond passive storage and into programmable financial infrastructure? In this episode of Dads Gone Crypto, Sean and Ryan sit down with Orkun Mahir Kılıç, co-founder of Citrea, to explore one of the biggest emerging narratives in crypto: Bitcoin DeFi, also known as BTCFi. Watch it here: https://youtu.be/UwHubc0RSc4 Citrea is building a Bitcoin Layer 2 designed to bring lending, stablecoins, settlement, and capital markets closer to Bitcoin itself. We unpack what this actually means, how Citrea’s ZK-rollup model works, why trust-minimized bridging matters, what ctUSD could unlock for Bitcoin liquidity, and how institutions may start thinking about BTC as productive financial infrastructure rather than just a treasury asset. We also discuss the risks: bridges, wrapped assets, TVL confusion, incentives, user safety, privacy, compliance, and whether Bitcoin can support a financial ecosystem without losing what made it powerful in the first place. This is not a price discussion. This is not financial advice. This is a deep educational conversation about where Bitcoin could be heading next.
