Bitcoin has value because demand is increasing and supply is increasingly limited,

The bitcoin economy continues to grow as more and more users own bitcoin, trade them, invest in them and use them as currency. There are only 21 million bitcoin created and so far not all of them are circulating in the market. While some are lost due to user negligence and others, bitcoin is more likely to be said to be increasingly rare.
I'm quoting something that might help the OP to find an answer to his question and also helped him gain some understanding of
[why bitcoin has value], because basically it's a common question that gets answered often:
Why do bitcoins have value?Why do bitcoins have value?
Bitcoins have value because they are useful as a form of money. Bitcoin has the characteristics of money (durability, portability, fungibility, scarcity, divisibility, and recognizability) based on the properties of mathematics rather than relying on physical properties (like gold and silver) or trust in central authorities (like fiat currencies). In short, Bitcoin is backed by mathematics. With these attributes, all that is required for a form of money to hold value is trust and adoption. In the case of Bitcoin, this can be measured by its growing base of users, merchants, and startups. As with all currency, bitcoin's value comes only and directly from people willing to accept them as payment.
