Bitcoin was created in the bid to find an alternative to paper money and a means of transaction that is totally controlled by the owner without a third party regulations or involvement, be it an individual, government or organisation,

To build something that can shoulder this level of responsibility, the quantity has to be much and circulation has to be everywhere, but to a very large extent the coin failed in this regard, the quantity of btc available and in circulation is very limited, and since more and more people are liking the idea of this alternative means of transaction, more and more people are coming into the space daily thereby increasing the demand for bitcoin that is already limited in supply which directly impacted the price and the value sky rocked and some persons who have in lare and small quantities decided to hold it for longer without selling since the value will keep rising over the longer period of time thereby causing more shortage in supply and increment in price..
  .so no one can blame anymore making a profits out of bitcoin as it only came natural with shortage in supply and increment in demand of bitcoin over time
