Payment systems are constantly changing. Bitcoin is the result of this change.
So Bitcoin is a real payment system. Yes bitcoin is a money.
Over half of the human population on this earth there is a set of people who are still unable to use the technology correctly, the most basic thing that they use is for paper money and coins, I agree with you about bitcoin is the currency that is highly prospective, but the balance the world economy still need to be using real money.
Until now I am still optimistic about the development of the paper wallet, and even tend to be in the future we use metal coins wrapped in gold and silver also for bitcoin.
do not have the power to do that. The government has their own money depending on what country your are living
and that is the only one that will be recognize as legal currency.
