I think that people are just way more realistic than you are. Every system has its own flaws and points where it can be improved. It is just that bitcoin is the same as fiat but in some points it is better. So if you point out flaws of bitcoin but they are also present in fiat then this is the obvious reaction. Bitcoin is simply a modern fiat currency with a hard cap. Also it is a legal tender in some countries.
Yes, that's the mantra. But but bitcoin doesn't exist just like a lucrative businesses don't exist in traditional ponzies. You're mantra is therefore just a nonsensical repetition of propaganda and fantasies.
