The difference of bitcoin and real money, physically bitcoin is virtual currency. It doesnt exist in the kind of physical form that the currency & coin were used to exist in. Bitcoin is something that people likes because you hold it by yourself and have better security some people also says that for you to escape from the bank. And lastly bitcoin has no value, only exchange value.
I agree with what you say. But bitcoin has value. As in other exchange tools, people's demand for value in the bitcoin is determined.
There is no value in your money if you look at your side. Then it is not worth under.
People can use different exchange tools during shopping. Bitcoin is one of these exchange tools.
There is no difference between bticoin and real money.
