Bitcoin is really a true currency/money. Why? because once you have it you can convert into a real money according to country you belong. And the banks also accepting bitcoin whether you are in different places of the world. In that case it shows how bitcoin is very popular in online business.
In fact, bitcoin is digital money that you can use in different transaction in online like paying bills, shopping in online market and more. In addition to that, you can also convert your bitcoin into fiat or real money that you can use in offline store.
