Money is unreal, meaning imaginary, intangible - a concept.
Currency is NOT money, but merely represents money.
So, bitcoin is... ?
Actually bitcoin is a currency, an electronic currency but stands as a money as well because we can spend it like a money though it is not that often to used as payments. When we say money, it is somethings that we use to buy things and get things we want. And as we can see, using bitcoin can do the same as money, you can still buy things you want from bitcoin. Thats why bitcoins are voth currency and money.
Bitcoin was created to help those who want digital money and now bitcoin is top on trends everyone is investor and getting maximum from bitcoin and basically it was introduced as alternative of currency but now it has become investment which is very profitable and people are really crazy about bitcoin now and I personally think that bitcoin will take over the currency world and will give us chance to use it all across the world.
