Nowadays we do not use paper money anymore. We do all our shopping online. We do not need paper money for clothes, food, etc.
Payment systems are constantly changing. Bitcoin is the result of this change.
So Bitcoin is a real payment system. Yes bitcoin is a money.
you cannot deny the importance of paper money i think it is much more important than bitcoin or any other crypto currency. yes the online shopping is pretty popular but i think the importance of real money in daily life is not denyable. most of the people are using real money instead of bitcoin for the online shopping. they are unaware of anything like this. yes bitcoin is a new concept but i think it will take time to be popular.
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.
