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.
If security is your concern i suggest you dont go out in the open flashing the content of your wallets. Surely if you do this then you are attracting criminals.
To make it simpler, bitcoin would definitely have an impact in economy because it is profitable. Anybody who gains profit would uplift ways of living and imagine if a lot is into bitcoin, definitely it would somehow boost economy.
