Oh yeah, imagine banks suddenly switching from having to store tonnes of gold in extremely safe deposit boxes to having everything on a little cold storage device that could be not only moved in an instant but also replicated from bank to bank, recovering any of the funds in case of any kind of emergency.
No more trucks and planes filled up with tonnes of gold. All within a single click. It's all a matter of time before it happens.
Imagine how far less resource intensive it would be for banks and central banks worldwide, not needing to move metric tons of heavy metal. And people like to cry about Bitcoin using too much energy(that's actually mostly renewable energy) lol.
