There’s a saying in sales: The confused mind always says “no”. I don’t understand the basis for the value of this virtual money, therefore I don’t use it.
Basis is as simple as the value of anything/everything: supply & demand.
New markets for new things are created all the time when there is a demand for something new that did not exist before.
Bitcoin has value because it is a new “thing” that has immediate value because all fiat currencies can be manipulated by governments. Bitcoin cannot be manipulated - yet.
Value of gold is similar: supply & demand. EXCEPT that governments can and do manipulate the value of gold by holding it or releasing it into the market.
As the number of Bitcoins is forever limited to 21 million, it cannot be manipulated or controlled.
Smart money people all over the world are looking for an investment that cannot be manipulated. For now, looks like Bitcoin is it. Demand is there - thus the price. It cannot be stolen and is more secure than the dollars in your pocket.
