The problem is that it has potential to change world for the worse, not the better. Fixed supply monetary systems have been tried in the history and there are reasons other than evil bankers wanting to get power for their dismissal.

And claiming that bitcoin's success would be bankers loss indicates that you don't quite get what is the utility finance sector creates. One of the main things banks do is they convert short term deposits to long term loans. There is nothing in bitcoin that reduces the need for that service in our economy. There were banks at gold standard times and there will be banks in the extremely unlikely world where bitcoin is main currency in a society.

There is no mechanism in bitcoin that would manage the volatility of the currency (against the price of bread and butter, not other currencies) That in itself makes it DOA as a proper currency. Further, even if that was sorted out and a society would want to have bitcoin as their currency, why the f*ck (pardon my french) the society would want to give the seignorage to bunch of cryptonerds? It is not like it is difficult to make a fork.

I am not mad about missing one more tulip bubble/ponzi scheme. I am mad that people never seem to learn.

Modern money is debt. It is a marker who in the society is owed and how much. Thinking that those markers should have fixed supply is just not smart.
