^ The simplest answer is because of the demand and the supply, that's it.
BTC has no government backing and no system of intermediate banks to spread its adoption. What makes it valuable is that it allows people to store large quantities of their wealth, spend, transfer, and earn a lot of money out of investing time and effort where digital currency is possible and while the supply of the BTC is limited to 21 millions which is the more people will hoard the more BTC becomes expensive.
