The reason for increasing Bitcoin is that more and more people are aware of Bitcoin, and more and more countries are recognizing Bitcoin as a valid payment method. Typically, whenever a country accepts Bitcoin as a legal payment currency, there will be a significant upward swing, as a large number of Bitcoin users are known, with only 21 million Bitcoins on the bill. This figure, which includes both exploited and untapped numbers, is expected to be fully exploited by the year 2140. Thus, the number of Bitcoins is limited, no more, including its founder, So, the more people use it, the smaller it should be, the more expensive it is.
