First one to hack the bitcoin blockchain wins
I'm crypto-neutral and quantum-skeptical but this seems like a legit threat.
The other major cryptos have moved to a proof-of-stake which is more centralized, but also more flexible. For example I can easily imagine ETH upgrading to post-quantum cryptography.
But Bitcoin is much less flexible. It has never evolved past proof-of-work. It's much harder for me to imagine a unified upgrade for post-quantum BTC.
I mean, your non-upgraded coins being worthless should be a pretty solid motivator.
