The value of Bitcoin will amaze everyone in near future. There are several reasons which are backing this :

Bitcoin is a decentralised currency with almost negligible transaction fees. Imagine the current scenario where Exchanges like Payza,Paypal takes upto weeks to transfer payment overseas. But with Bitcoin you can simply sent that payment within hours.
There is no central authority controlling Bitcoin so there is no chance of destabilising the economy by banks or sme other Government institutions as they do it today.
Demand will increase as the market cap on Bitcoin is 21 million and all the Bitcoins will come into existence. So there will be a drastic surge in the demand of Bitcoins in the near future which will increase the price of Bitcoins. As per http://Blochain.info the price of Bitcoin is going to hit 20000$ by end of 2017 !!
