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.
This is hard because not everyone can earn Bitcoin free. If you invest in Bitcoin, there are too many risks, and you can not be sure that if you invest in it, you can make a profit.
