TEN YEARS AGO SECURE BITCOIN COLD STORAGE WAS DIFFICULT. FIVE YEARS AGO SECURE BITCOIN MULTISIG WAS DIFFICULT. BOTH ARE INCREDIBLY EASY NOW AND USERS TAKE IT FOR GRANTED. IT IS HARD TO IMAGINE A WORLD WITHOUT EITHER. NOSTR IS YOUNG. KEY SECURITY WILL BECOME EASIER AND MORE ROBUST SOON. THEN WE WILL ALL TAKE IT FOR GRANTED WHEN ANY INDIVIDUAL, COMPANY, OR GOVERNMENT CAN USE MULTI DEVICE COLD KEYS TO BROADCAST TO THE GLOBE WITHOUT PERMISSION.
