For me, bitcoin is not money. It performs the functions of gold, payment of the system and cash. Bitcoin is something in common with what I called.
I agree it's tempting to see bitcoin just as an asset. But i've use bitcoin as a currency too. So yeah it's not only a fact that bitcoin is a currency but it's also how you treat it.
Buying stuff will give you the feeling of how it is money and believe me there is plenty to buy with bitcoin.
