This circle is really quite magical. During the bull market, you could find "ecosystem disruptors" and "tech pioneers" everywhere, with a rising wave of calls on Twitter; when the bear market hits, these people run away very quickly—either disappearing completely or vanishing after pulling out their funds. But there is one team that deserves special attention, the APRO team that was mocked by everyone last winter for "still working on infrastructure."

What was the environment like back then? Bitcoin was crashing hard, liquidity dried up, projects collectively cut back and slashed budgets, and the community was daily spreading FUD. Every little movement could scare away a bunch of investors. The normal approach was to shrink the scope; survival was more important than anything.
But APRO went against the grain. These people are like madmen building houses in a snowstorm—others think they’re crazy, but they see it as the best construction season, with no noise or interference, allowing them to lay the foundation into the bedrock.
What exactly are they doing? Simply put, they have one ambition: to make Bitcoin not just "digital gold," but also capable of lending, derivatives, and complex financial instruments. This is the hot BTCFi track right now.
But what’s the problem? The Bitcoin chain itself is "dumb." It doesn’t know the outside prices. If you want to use Bitcoin as collateral to borrow USD, who tells Bitcoin "how much is 1 BTC right now"? Wrong data feeds, and the protocol gets exploited instantly.
APRO’s core work is to serve as this "information relay" and "bodyguard." The key is that they didn’t just copy existing Ethereum solutions but instead designed a dedicated solution specifically for the Bitcoin ecosystem. That’s the hardest part—adapting to Bitcoin’s constraints while ensuring security and efficiency.
While everyone thought the bear market was a season to lie flat, this team chose the most difficult path. Today, BTCFi’s popularity owes much to the infrastructure support behind it.
