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.
Oh so you probably won't be "stuck" with that many BTC left after all if you use the dangerous tool of the emergency address; maybe you can only send to those who made a payment with the emergency address or received a substantial amount on it within the last month or two so you know the investor probably still have access to the address
Then the rest of the money could be send to an escrow as explained in my previous post
