It is a currency, no doubt about that.
I guess what you are really implying to is about the usage.
Yes, that is one problem in many cases of crypto currencies also in altcoin section.
Merchants are still doubting the usage of crypto currencies specially Bitcoin.
The volatiliy is still their one of the most
Thats right, in the outer packaging of bitcoin is currency, there is no doubt about that. but we know that only a few merchants accept payments with bitcoin, even we are very difficult to find it right? so do not be surprised if many people still question the actual function of bitcoin?
I think the reason why many people has not really seen much of its payment function is because we still concentrate on the store of value benefit of it, so you find many people who are demanding for btc doing so keep it in their wallet till bitcoin is completely mined with the believe that by that time, bitcoin would have grown very much to yield them enough profit, which by then you will see an increase in its usage because everyone must have accumulated enough of it by then.
We actually have some merchants that are accepting it, I have seen a lot of them around, and I have seen some even out the payment method on their ecommerce website, so it’s with time that merchants will grow, when bitcoin is no longer servicing as store of value that much when the price becomes stable.
