I believe he had a lot of preparation. Including this one, I think we have been thinking too much about how to help him. Just donate and wait for the money to be used sometime in the future

(Or it is always there

).
I think that Bruno knew that the funerals wouldnt be that expensive, had enough money for the coming events and may have organized the private keys to be delivered to his family using a delayed email service planned for like 6 months from today or maybe a 30 days rolling one.
A little bit like a dead-man switch.
He wouldn't be perverse and make the coins lost for everybody (especially his family).
Anyway, a great bitcoinner was lost.
Rest In Peace.
PS : I'm just surprised that someone that started in 2011 and has been so prolific here isn't worth at least 1 million usd.
