I would be quite worried about advances in quantum computers if I had any Bitcoin after watching this DEFCON talk: https://www.youtube.com/watch?v=OkVYJx1iLNs

Every time I mention quantum computing as a threat to crypto (which I have been for years), I get downvoted to oblivion. I guess we have a lot of HODLers here. A bet on crypto is a bet against quantum computing.

I haven't seen anyone post any progress on factoring large numbers with quantum computers in a while. Annealers won't do it efficiently, but probably still hold the record anyway, for a relatively small number you could do classical hardware. Gate model machines with enough qubits to do it are still ages off. Bitcoin should find a way to transition to a post-quantum algorithm, but that's about it. As long as they do it before anyone has a big enough QPU, they're fine, and nobody is even close, it seems.
