Bitcoin is not money.
It is more an artwork with 21,000,000 limited editions. And each limited edition contains 100,000,000 limited pieces. (satoshis)
That is how I see it. Bitcoin is not money. It is rather an asset like gold, silver, diamond and other precious mineral. We buy and hold it. We sell it when the price goes up. Aside this, I have not seen any other case use of bitcoin.
