Much sooner than it\nis believed QC or Moore's law could impact bitcoin.  Changing bitcoin so as\nto require that early coins start getting \"scavenged\" at that date seems\nunneeded and irresponsible.  Besides, your ECDSA is only revealed when you\nspend the coins which does provide some quantum resistance.
