Where does the US Dollar go when you buy a bitcoin? Not From Anyone but from CoinBase ect. Ok, So I see A lot of people say that the bitcoin when purchased from one person to another that money gets sent to that other person in exchange for the BitCoin. Example If Bob has a bitcoin for 10 dollars and sold it to Jim, Jim would Pay 10 dollars to Bob for that Bitcoin. So what happens to the dollar when someone buys a bitcoin from cryptocurrency market. That money doesnt not vanish, so where does it go? It has to go somewhere. Its really confusing question hopefully someone can help me understand. Thank you.
When you buy a book from Amazon (directly, not from its marketplace), who gets the money?  Amazon gets it.  They can use the money to buy more books to sell to other customers, pay their employees, power their servers, etc.

When you buy Bitcoins from Coinbase, who gets the money?  Coinbase gets it.  They can use the money to buy more Bitcoins to sell to other customers, pay their employees, power their servers, etc.
