If you consider profit from investment is part of your income, Bitcoin can bring passive income. It is a term and can be used depexently on each person's view. I don't think it is too important to have an agreement on which term is correct, which term is inaccurate.

I consider Bitcoin profit as my income and it does not mean I don't have to work. Buying, holding and securing my wallets and wallet backups are sort of works so it passive income for me.

With government, they surely consider it as capital gain as they enforce Capital Gain Tax on us.
