for a second I thought it was going to be some modern art empty canvas bs. Glad to see it's not ! 

 Hopefully (and certainly if we are to go mainstream) there will be structures to satisfy both the self-custodian needs of individuals as well as institutions. Maybe there are already there but I am not aware. How likely would it be with the current structures that say "google" is able to buy and HODL BTC? Technically everything is there for them to do it, but maybe the (intentionaly) complex reality of finance makes this unlikely?
