I think Bitcoin is helpful to the economy because it helps the people, may they be employed or unemployed. It helps the people to be productive especially on their vacant times or when they are not working. Bitcoin is getting a lot if attention in many countriesnow because it really helps the people.
As for me, bitcoin don't directly help the economy but rather has a big impact in it's growth. As the people in the society succeed and grow in their financial stability, the economy grows as well. Each individual who uses bitcoin influences the development of the economy.
