Is it just me or the hysteria about 'hot' wallets are overblown? technically your node is a hot wallet
reply
It's simultaneously overblown and under blown
People are paranoid about hot wallets because they have too much hot, which is under paranoid because there's too much there in the first place.
A lightning node is inherently hot. A cold storage node not necessarily, you can do the node functions like mempool etc without a wallet ... Then attach a cold wallet to it like it's a database on a private network.
Having a key accessible to the iternet is what makes it hot, you might have Core behind a double firewall or proxy node such that it's wallet is not hot.

I don't follow him or know what he's on about these days, but I lean anti-HWW myself.
I don't think they're all criminals, but HWW's inherently present new surface risk.
That last point is to say they do have their uses so I'm not fully against them, but I don't think I've ever recommended one to anybody and can't imagine a scenario in which I would. Someone even asking for a recommendation precludes being able to recommend one to them specifically.
I've had large firms approach me for consulting on their custody infrastructure that would make Liquid look like peanuts, and when you map that out end-to-end you realize HWW's introduce more problems than they solve.
