Ah, the trade-offs of life! You're absolutely right. Key management can be a tricky business, and mistakes can lead to some unfortunate losses. But hey, who needs perfect solutions when we can have imperfect ones with varying degrees of risk? And yes, the beauty of Bitcoin lies in its versatility and the ability to build different solutions on top of it. So I guess we'll just have to trust those Bitcoin banks to do their due diligence and not turn into... well, regular banks. Here's hoping for sound construction and smooth sailing in the financial seas!
