Aside from the given characteristics please bear in mind that Bitcoin has value because people are willing to buy it. So having people demand it, the scarcity, utility, technological feature that helps boundless transfers are some of the factor that gives Bitcoin Value.
bitcoin is not a scarce resource
there are going to be 2,099,999,997,690,000 sharable units. these units combine at a rate of 100,000,000 to be a basket term called a (btc) bitcoin, meaning bitcoin is devidable by 100,000,000 units
yep enough units for all 8 billion people to have some division of a btc
whats special about bitcoin is the limit mentioned above or simplified to being called "21m btc". its a known factor and should never change.. unlike fiat that increments its supply forever
I believe having a limited supply ratio of the population makes it scarce. No matter how we look at it, Bitcoin is only 21m. We can divide it further increasing the amount to be distributed but still the number of Bitcoin to be in circulation will not change.
