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.
Well, actually the bitcoin itself would not have to be considered a source of wealth if we observe it as a currency, just as the dollar or the euro themselves can not generate any wealth. What is generating wealth, in my opinion, is the effort and talent of many investors who have decided to bet on business related to bitcoin, as well as the great volatility that the same investors are generating in this lucrative market.
