The way you telling is trading. That doesn't mean BTC decreases unemployment. If you think BTC as a money how money can reduce unemployment without any work?
Basically, every individual living without an average income is considered as unemployed because there is no company that pay in exchange of its work but because of bitcoin there are many people around the world gaining extra income therefore they are good to be entitled as self employed between crypto and itself and even those employed people in a corporate company are eventually quitting there work and choose bitcoin earnings because they found out that bitcoin has more opportunity that can fulfill there financial dream in life.
Bitcoin doesn't create more money for the world, it needs to has the supply from FIAT invest to the cryptocurrency market to has high value in the market. Where's for this supply? From the investor, from the salary of the investor.
No job, no high price for the Bitcoin value. And finally, those who gave up their job to start make money from Bitcoin will be the unemployed because they haven't any job to work + money earned from Bitcoin isn't enough for their life.
