Is it reasonable to assume that many wallets won't get migrated and could eventually be seized by whoever (eventually) possesses a sufficiently strong QC? If Larry Fink is right, then that could be untold billions, assuming for sake of argument BTCUSD goes to $1,000,000 by the time such a QC is feasible.

If Satoshi Nakamoto did lose his keys to those treasure trove wallets, those will be up for grabs, as will anyone who lost keys.

Perhaps hoarded encrypted PCAP's aren't the only motivator for quantum opportunists.
