In the end all bitcoins will be lost
In theory the maximum supply of bitcoins will be 21 millions, however everyday someone forget their password and lost access to his wallet. So, there is a non zero rate of bitcoin loss forever. Eventually, all bitcoins will be lost. So, even if you are a fanatic and believe that crypto is the future there is a huge insolvable problem in bitcoin. For me this is the proof that bitcoin can never work and will only be a Ponzi scheme.
