Bitcoin gives freedom and privacy to it's holders that is why they're at liberty to either spend it as a decentralized digital currency or they can hodl it as an investment asset. Bitcoin is a new innovation in the financial system and it's not even two decades old, so you can't expect it's usage as a currency to be compared with fiat just yet, you have to give it time. I believe that in the near future the naretive about Bitcoin by those that are still skeptical about it will change, it's already happening, the adoption is increasing geometrically. Some businesses have started to accept Bitcoin, gradually more will join as the awareness and adoption continues to increase. Remember that great things starts from small beginnings and it's sad that Rome, wasn't built in a day, so it's not too late for you to hop on the train.
i appreciate your detailed comment, i agree with you on most things, but one thing is still a problem - the usage. The normal, everyday user doesn't know (and doesn't want to deal with) securing their coins in cold wallets. Once a mistake is done, the money is gone and no one can revert it. And it doesn't seem like the bitcoin community even cares about this problem. Decentralization solves some problems, but creates other problems.
