Just like normal money. I want it both. You can spend it and you can also keep it and save it. There's should be no walls in doing it both since it is discovered that way. A currency.
The problem is not with Bitcoin but to those who uses it. These days, buyers of Bitcoin will think of it as an asset. They only buy it for the sole reason of keeping it.
But it's not like we can blame them. There's very rare retail shops who accepts it and even big department store companies don't have a Bitcoin option for payment. That's where it should change.
