For most of human history, some physical object was used as the store of value. The function of value storage did not need a physical manifestation, but having one allowed for making the supply of the store of value harder to increase. Bitcoin, by not having any physical presence, and being purely digital, is able to achieve strict scarcity. No divisible and transportable physical material had ever achieved this before. Bitcoin allows humans to transport value digitally without any dependence on the physical world, which allows large transfers of sums across the world to be completed in minutes. The strict digital scarcity of the Bitcoin tokens combines the best elements of physical monetary media, without any of the physical drawbacks to moving and transporting it. Bitcoin might have a claim to make for being the best technology for saving ever invented.
