after all, if there is a better function why should you regret other functions that have not fully worked? after all, the problem is only because of regulation, so the function of bitcoin as a means of payment cannot be maximized. but as time went on, adoption continued to grow, some big companies started making discourses for alternative payments using bitcoin or crypto. if this is really realized then it will be even better for the development of crypto.
After all, everyone has different tendencies, some choose crypto as an investment tool, trading commodity, and a means of payment.

Bitcoin can't be limited within a small space, it has evolved as a multi-purpose asset than a payment/investment asset. The purpose on which it got developed is to give financial freedom, but the usage happened on illegal activities and on gambling in the very beginning days. This gave bitcoin a bad image, and later things slowly started to change through its growth and people started believing in it. This way it has got different purposes and it depends on the users.

Bitcoin isn't strong as currency because most businesses don't accept it as payment and not because transactions take too long to get confirmed. There are many things I could pay with bitcoin and wait several hours or even days to have my transactions confirmed without any problems, but unfortunatelly I just can't. So I have to exchange my money into fiat first in order to use it, what is very pointless since I could be using that money in bitcoin. I believe if more services adopted bitcoin as payment we would see an exponential increasement in btc usage as currency.

However it's important to highlight I'm not talking about any kind of services. It must be daily high demanded services and businesses by common people, not some fancy or excentric brands.

There are many ways to develop Bitcoin. Can be used for education, investment, technology,
Because of the emergence of the Lightning Network, Bitcoin can be used for daily payments, but some people will insist on holding it because of the value of Bitcoin.
Bitcoin is becoming more and more valuable, so more people invest in Bitcoin,
This is a good aspect. I don't think it has lost its purpose.

It's really used in both ways and at the same time, they work synergistically. When the demand on bitcoin for investment purposes rises, the number of transactions increases too.

But right now, I think that there is more demand on bitcoin as an investment form. And the quality of investors is very low, I mean, a lot of people enter the bitcoin market blindly and have no idea what it exactly is or what's the purpose of this coin, they just blindly follow other people.

Bitcoin lost it's purpose but it has nothing to do with the demand on bitcoin as an investment vs bitcoin as a payment form. The real reason is that Bitcoin got very regulated, people don't use it to get rid of 3rd parties, instead, we demand on them when we use crypto visa cards, exchanges, commercial payment gateways, etc.

- Bitcoin has had independent purposes for many fields to enhance anonymity and security as well as provide payment value but individual bitcoin's original intentions have been disrupted by too many of us, turning it into an investment tool and erasing its personal footprint. Bitcoin has ceased to be a traditional version and maintains the old independent thinking, it's become a full-fledged investment in a sense, the old purposes haven't gone away but you or many people also realize the dwindling of these purposes, only used to advertise as feature variety of bitcoin
