I agree.
Anyone who claims that Bitcoin is a Ponzi scheme either doesn't understand how Bitcoin works or doesn't understand what a Ponzi scheme is, or both.
The sad thing is that more than 15 years later the same "arguments" are being used without any increase in knowledge. Look at slashdot.org from July 2010 and you will see the same type of stuff being said. The smugness everywhere by people who are clearly uninformed about many details is ridiculous given the amount of time that has been going on.
I can kind of see from people like Buffett and Munger since they aren't known for their technical prowess and even if they did understand they are beholden to the authoritarian powers who don't want people out from under the thumb of government but a lot of these people should know better. The fact that they don't indicates to me that they are willing to sell out themselves and their populations for power.
