Make no mistake, Bitcoin’s intention is to become a P2P electronic cash system. If people only invest in Bitcoin because they think its going to make them rich, then its a typical sign of a bubble.
Reading the white paper of bitcoin and correlating it with today’s usage of it, I can agree that there have been a paradigm shift of the main problem it was coming to address and that was/is majorly because of the reason that the transaction scalability isn’t smooth as many would want and also the high cost of transaction fees sometimes incurred. To me just like bitcoin is pseudonymous in nature same way that it’s usage can be, you can take the advantage of it been an hedge against inflation and hodl or use it as a currency just like fiat. Personally i will treat it as an alternative to the fiat currency, make use of it when the fiat currency creates hurdles.
People aren't really "using" bitcoin and probably never will. As a currency it sucks, but long-term holding as a store of value is where it excels. Everyone should be aiming to just hold a as much as they can afford for as long as possible.
As a currency it doesn’t sucks just that the use of it as currency hasn’t grown much which I will basically blame on the adoption rate of it, if the rate of it’s acceptance as a payment method grows then you will see more people turn to make use of it more.
