Both options are good, it depend on which one you are comfortable with. However IMO, I think it is good to diversify your investment among a few types of financial instruments.
Well I think that people love to do the job they make money in. For many people, Bitcoin would be attractive in the sense that it can give away sudden profits. Big and huge.
