From what I've read, money is simply described as our medium of exchange it is what we used everyday to buy everything we need and it is widely accepted, while Bitcoin is a type of money but it is not widely accepted, it can also used to pay or buy but for online businesses only or maybe, where it is widely accepted. We can keep bitcoins, we can also acquire them and they are still worth                  as they used to be, bitcoins can be converted and can be bigger as it should be.
