2- Natural selection can only operate within a closed system, and bitcoin creates this closed system
I think your analogy is a little out of the equation because natural selection never applies to supply and demand relationships. Forget the parable you are trying to convey because bitcoin is seen as neither an open nor a closed source of natural law equations.
3- (conclusion) - if bitcoin is a closed system, because of the proof of work, then the laws of natural selection apply to bitcoin and in the long therm the losers are removed from bitcoin and this forces only the winners to remain, and the price will go up
The slight similarities may be true, but these factors cannot be proven in fact so that we can equate them. Even though I have learned about the laws of nature, how the strong survive and there is no justice there as expected. I want to know your opinion, what does losing mean? Because if there is a competitive relationship with other coins, currently no one can compete with Bitcoin, so there is no need to look at the process in the long term.
