BTW, how much BTC is there that cannot be sent to an emergency address or will not be sent soon to users that cannot access their account because of F2A?
I've not counted that up. I don't have a list of accounts which are having trouble with 2FA, I just use the ticket system. I trust that the affected users will remind me when it's time. I checked the top 20 outstanding balances yesterday and was happy to see that 19 of them have emergency withdrawal addresses specified, so that's a good sign.
