You say that wealth is not stored in currency because you are aware that Governments can rob that wealth by devaluing the currency. They cannot do that with bitcoin. Yes, there are thousands of scam coins that have disappeared. But there are legit projects that are going to change the world and you have no clue what is being done/worked on.
Bitcoin is not a currency, it is a store of value and more people are realising this.
Governments can print trillions of banknotes and make you lose all your money/force you to spend it before you lose it to inflation. All your criticisms of crytpo are actually criticisms of fiat.
