this fact goes against the very foundation of any successfully implemented mean of money anytime across recorded history.
The founder was saying Bitcoin is like a commodity, Bitcoin isn't must to be used as a currency.
After all every person has it's own choice to use Bitcoin for what purpose, if you want to use it to buy water that worth $1 and spend $30 for the fees, then I can't stop you for doing that.
But I use it as an investment since Bitcoin is very volatile.
Bitcoins have no dividend or potential future dividend, therefore not like a stock.
More like a collectible or commodity.
