My biggest worry about Bitcoin is that it's still on proof of work. Even if it has shown itself to be bulletproof, it uses as much electricity as a small country and I don't think the environmentalists are going to just let that slide.
Aside from the long term security guarantees that every Bitcoiner is just ignoring, the narrative around energy usage has pretty much gone away. Why? I have no idea. Ethereum in comparison has gone to PoS and reduced its energy usage to near trivial amounts while at the same time democratizing securing the network in a way more sustainable way.
