Everyone has right to express his/her opinion till it hurts someone. Your views about Bitcoin may stop you to buy it but many people still think Bicoint is worth buying. This is only the investment which can grow multiple times with time as compared to any other investment, of course the same level of risk is also involved. I am still in favor of buying Bitcoin at dips, Bitcoin still is widely accepted and it number is continuously growing. Its only the demand which decide anything's price.
