Different people have different opinion but I think bitcoin is new part of  strong currency. We need some help from government or national security for monitoring and providing strong  security for those people who are working into this sector. Even more people are affected by various criminal attack that  reduce  and demotivated to work in online earning.
Now times are changing by the help of different online currency trough which people can earning money and invest these money in different sector for the purpose of getting profit. 
In future proper security and more effectiveness of virtual currency  can contribute economical development.
