Personally, I’m most concerned about the quantum computing risk to $BTC. Some say that if Bitcoin gets hacked, all bank accounts will be drained too—but that’s a one-dimensional view. Systems managed by specific organizations can quickly update their security protocols. As CZ said, it’s easier to encrypt than to decrypt—centralized systems can respond rapidly. The problem lies with networks like Bitcoin, which require consensus from a vast majority. Even the quantum-resistant proposal, BIP-360, hasn’t been activated yet, and there’s still no agreement on when or how to implement it. The critical issue is that over 1.7 million BTC are already in addresses where public keys have been exposed. What I fear more than Bitcoin being hacked is the market-wide collapse triggered by the shock of such an event. Let me be clear: Bitcoin is neither a perfect technology nor a perfect network. The longer upgrades are delayed, the more it becomes a legacy network rapidly falling behind. The very feature that was once its greatest strength—having no governing entity—has ironically turned it into the most vulnerable network in the face of quantum computing.
