crypto is a ponzi scheme because liquidity in it only comes from the next sucker buying in. it’s not connected to anything that generates or has value, you can only get out of your position if you can convince some one else to hold the bag. in a sense this is true of all markets but only in a very weak sense. assets linked to governments or value generating corporations will have value for the foreseeable future, you don’t have to race to find a sucker to liquidate your position
