Bitcoin is cryptocurrency and currency means money so, yeah bitcoin is money! It is a currency in its initial stage which has started to gain more popularity recently. Bitcoin serves as money to buy and sell things, but it is better than fiat as its price is increasing which is profitable.
I agree with you, because bitcoin is one stuff to earn a money. Bitcoin is another form of currency because it can use also in paying like loads online, and actually in trading that needs to pay the fee and I'm sure that the owner of that exhanger have an income.
And now it is another form of money cause it can earn through online and give a huge profit to the user who work hard in the crypto world.
And another proof is the other exchanger who accept dollar and use to exchange, which is a currency also. In that exchanger they have also a bitcoin and other currency.
