What's your problems with the current security of Bitcoin? I mean, it isn't inherently insecure, otherwise it wouldn't be worth anything. So, what specifically do you not like about it, or what security aspects do you want to improve?

Bitcoin is also almost infinitely scalable. Probably more so than our current mass preferred fiat system. So, there's that. Plus, it's already decentralised more than our fiat system, which already makes it the better option in almost all metrics. Cash isn't as secure as Bitcoin, and I'd argue that electronic money, i.e those that are stored on banking systems also aren't as secure.

So, I'm struggling to really see current problems, but would like to hear them.
