Yes, maybe it is not the literal money that we are used to see but it is one of the medium of having it (money). Things, raw material, anything thats we can do buy and sell is money. Gold, silver, etc is source of money. As well as bitcoin. If you do or participate in some forums here, and also investing and trading well probably you'll get higher amount of it. And aside from that in every business has a 'money' which cycles its own life. And since bitcoin is one of business, therefore it is manages by money which has exchange of money. Complicated, but in simpliest word in the world of business money or profit are the major present in it.
