Do you agree with me that those who sell bitcoin are losers, and those who buy and keep bitcoin are winners?
No, I don't agree with you. How can those who bought bitcoin be winners? What did they win?
If you are talking about the markets, the only way to win is to sell the asset at a higher price than the price you bought it for. But according to your definition, those who sell are losers, so you contradict yourself.
Natural selection removes losers from the system
Not always. There are countless studies that have confirmed that in the evolution of species, the best features do not always win.
If bitcoin is a closed system it uses natural selection, and then it will have more winners than losers, so the price will go up forever
Bitcoin market is not a closed system. It interacts with traditional finance and other cryptocurrencies, new bitcoins are constantly mined, and people can enter and exit the market with fiat currency. This continuous flow makes Bitcoin an open system, not a closed one. But maybe you are confusing the concept of a closed system for a zero-sum aspect within Bitcoin market. Those are completely different things.
