Yes they can.
At least a few million people classify it as money.
I treat Bitcoin as money. Others don't. Not everyone accepts Euros either.
The problem is; they (or a man) classified bitcoin or cryptocurrency as speculation tool or subject to manipulation.
Whatever they said, it's not so important as most people consider bitcoin as an alternative currency, but currently being used as the speculative object of investment.
IRS has stated virtual currency as property for the US Federal tax itsoses, fortunately, they didn't ban it and people are free to use or trade it as long as they pay the taxes.
I consider bitcoin as money as well, but there is no any merchants accept bitcoin payment nearby to spend it.
So, I will just keep my bitcoin and use fiat currency as means of payment

Bitcoin is actually the manipulation tool, but who cares?! It is bringing a real profit to those who can handle it and while it is so it will be in demand.
