There is a similar thread same with this topic. Bitcoin will not eliminate unemployment. There is no forever profit in Bitcoin without having a regular work whose supplies a money to support Bitcoin activities such as mining and trading.
Yes thats true, we should not dependently live with Bitcoin cause profit here were not for a lifetime and we should deal with the fact that a stable is a better way to have stable profit, you know its like the same with Bitcoin but still can finace your expenses.
Income with bitcoin is not stable and it always use to change but it does not mean we can say bitcoin is not like a job. Bitcoin has good opportunities for earning money and taking benefit from bitcoin. Once long ago I was not having source of income but now I am aware of bitcoin resources and buying it, it is being use as job from signature campaign and investment as well.
