Bitcoin is like a rollercoaster and it is currently at the top, this should lead most people to conclude that a drop is due before it continues the upward trend overall. When it is swinging hundreds of dollars in a day, taking it as an investment is pretty much gambling like poker.
Yes,bitcoin is a decentralized currency uncontrolled by any one.Unlike gold,whose price is controlled by world gold council,bitcoin price fluctuates as per increase and decrease of demand for bitcoin.Bitcoin is definitely like a roller coaster.When its price increases,its investors get happy and when its price decreases,investors feel sad.
