I consider that any coins up for grabs that don’t move to quantum secure addresses to be a prize to whoever achieves quantum supremacy first.

Also only coins in old P2PK addresses, and P2TR addresses are immediately vulnerable. Also any coins in other addresses that have been re-used (ie: already spent from).

Any addresses that are a “pay to hash” type are safe from immediate threats up until an attacker has a quantum computer fast enough to derive the private key in the time between when a payment is broadcast until it’s included in a block, since the public key isn’t revealed until it’s spent from. So coins lost forever in these addresses will likely remain lost forever.
