The reason is simple. I feel the supply of Bitcoin at pegged 21m will be too limited for the global economy.
What makes you believe that 9 million changes in supply are enough for the global economy? Why the current number is not enough anyway? Any calculation whatsoever or this is just another gut-feeling?
Actually , I believe that Nakatomo Satoshi is one of the powerful manipulated whales in this market. he's just hiding his identity to control this market and make lots of money. If he wanted to be good for bitcoin, he would have upgraded bitcoin before and wouldn't let bitcoin be as slow as it is now. From the beginning, he wanted to create a genuine Defi, not a place to invest in technology.
Your conspiracy theory is interesting. I never knew satoshi was such a powerful man.
