Bitcoin has value because many people use it and want it, see it as something of value, and use it as an investment or other use.
and if everyone stops using bitcoin in any form then the price will drop drastically and therefore will not earn anything.
and the value of bitcoin is also determined by the forces of supply and demand and is also limited.
That’s exactly the point ‘what if’ everyone stopped using it.
Though it’s a digital currency that has no physical existence, it is publicly traded around the world and has intrinsic value. Many companies and even brick-and-mortar stores accept payment in Bitcoin and hence, it holds real monetary value.
