Bitcoin can really make people greed because we can earn money through online system and we can earn even without going outside our house, it is easier to earn than outside yes, but we still need to have a good knowledge for us to achieve and to have a good earnings. Bitcoin is now falling but I still believe that bitcoin will improve its price. I believe that until bitcoin has a stable value, it will not be used to the full. Absolutely rightly written in this topic above, until its price is unstable, it will be used only as an investment.
