That's right, we need more time for Bitcoin to show its potential. But I just think it should fulfill its role, which is to help its holders reduce their risk of inflation and not worry about its value in the long term.
As for being a common currency in payments it shouldn't be. Because we still see a huge fluctuation in Bitcoin's value, and it would be very inconvenient to use it to pay for any product. Think about the fact that before you leave the house, the Bitcoin in your wallet is worth $ 100 but upon arrival at the store, the value of the Bitcoins in your wallet drops to $ 90 because of its volatility . Nothing could be worse than that.
