Bitcoin is both a spending tool and a savings tool. However, without being biased, I use bitcoin more as a long-term savings plan. I spend fiat more than I spend bitcoin. There are lots of bitcoin enthusiasts like me who see and use bitcoin the way I do. The thing is, lots of bitcoiners have limited the use case of bitcoin to just investments purposes only. There is more to this than just investments and/or trading which we have all upheld than what it was originally intended for.
The original reason for the creation of Bitcoin is barely known by the newly joined users of this industry, at least most of them don't even know, or care, for what Bitcoin was created for, what the story behind it is, and what the vision of its creator was behind creating Bitcoin. This is mostly because they see that it's an asset that grows in value, and they think it's only for investments, you buy it, store it for some time, and then sell it when its price goes up, and voila, you got some profit for the money you had used.
I don't blame them, though. Bitcoin's limited supply and increasing demand have made it like this, and now there are fewer ways for us to spend our Bitcoin, and there is more motivation to hold them because we know that's at least going to give us something back in a while. There aren't a lot of places around the globe where people can spend their Bitcoin for convenience. In our country, there are none, I know of no places where we can spend our Bitcoin, also because Bitcoin is not legally recognized yet.
