I agree with you that long-term investors are intended for people who have permanent jobs. But you forget one thing that investors have offensive and defensive characters, which means that when the market is sluggish and prices decline they buy bitcoin, when prices crawl up they survive not selling bitcoin because the prices they think haven't reached the peak, once that point is reached, they sell and big profit. Well, this brave character is not owned by workers, but is owned by traders who are used to speculation.
