When you talk about Bitcoin first thing which most of us thinks either it's a get rich quick scheme or an investment scheme. Did Satoshi Nakamoto created Bitcoin as an investment scheme? No, it was supposed to be a peer to peer payment transaction across borders without involvement expensive money exchangers or regulators but it has been turned into an investment scheme, where are we heading ? Do you think Bitcoin is losing its original purpose of its invention?
No, this is not the case. Why bitcoin value increasing ? Because people are using it in their business and also as a payment method. Recent example is the Paypal supporting bitcoins. Since the supply of bitcoin is limited, people also hold it in anticipation of getting profits.
