I think money is best used for buying and selling not hoarding, we get to see the value more when using it.
This my thoughts, wby?
This is basically because bitcoin currently serves two purposes. One is to act as a currency for payments and the other is to act as a tradable asset.
The reason why people hoard bitcoin is because they treat is an asset which has high increasing value.
There are others who don't hoard bitcoin and rather spend it for payments because they treat it as a currency for method of payment.
There's no right or wrong here and it's just how a multi-value coin behaves I guess.
