It's most suitable as a long time investment and not a rolling income source, except you have a skill you can render as a service online to people/organization that needs it or here in the forum that you get paid with BTC and that can serve as income source.
people are more familiar with Bitcoin as an investment asset. That's the reality. those who trade may be able to benefit. but not as a source of income. They trade to increase the value of their investment in the future.
whereas you mean related to services or services that are paid for using Bitcoin. that's what we really have to choose. Bitcoin is an alternative payment besides fiat. I am still waiting for the day when the whole world will accept Bitcoin as legal tender for goods and services.
