That is a good question. well, My answer to the question about  bitcoin a money or a currency is. Bitcoin is a money. Know why?, because as of now, bitcoin is using for mode of payment of some stores abroad just like japan, china and USA. Money is a person has in his wallet just like bitcoin is also in our digital wallet. Compare to the Currency which is the money that a country uses and bitcoin is until now did not accepted by many people ,lots of people did not use bitcoin and some of them did not know it.

Thats why for me bitcoin is money because we individually use it even though some people is not interested.
