I'm not sure if Bitcoin is used as a currency now
From my perspective, Bitcoin as well as other cryptocurrencies remains and will remain mostly a speculative asset. It is unlikely that we are going to see much interest from institutional investors any time soon. Really, what's in Bitcoin for them? It will be a free lunch and easy money for ordinary folks like you and me. But that has never been the case in the past and won't be in the future. In other words, "local" people tend to overestimate the importance of the whole crypto universe. It is small and insignificant (for big guns)
Bitcoin is still more of a speculative assets this way because it has not yet been regulated, if bitcoin can get regulated, I think it will even be more beneficial to these institutional investors, and this institution will not only use it for investment purpose, but for digital payment purpose, which is the main goal of bitcoin, but I guess it will really takes lots of time for it to be regulated as the governments that is need to regulate it has not yet picked interest in it.
Anyway, their regulation is just to fast track the adoption rate and make it quickly become less speculative market, but without government regulation, as we gradually proceed in the usage of the technology by ourselves, a time will show up when bitcoin becomes a stable coin, and then it would be difficult to speculate it, once it becomes less speculative, institutions will tend to use it as means of evading task, and many more reason other than this.
