it is more like an investment now as you can see a lot of people r buying btc is just for keeping and not for spending. but to be used as a currency there also must have places where you can spend and this is a real problem as a lot of coutnry dont even have such places for u.
It's both. You can use bitcoin as an currency, but also use bitcoin as an investment.
To me bitcoin as an asset/investment is the main thing i am using bitcoin.
If you believe in the future of bitcoin, it will be adopted widely so that it will hit mainstream, then you need to treat bitcoin as an investment.
At the same time, if you do not want to save bitcoin can spend it like a currency.
