Bitcoins are not a legitimate currency because bitcoins are not protected by the government, and bitcoin is most likely used for bad transactions such as the buy and sell of weapons. Bitcoin has no policy retention from the monetary authorities Because bitcoin does not meet the liabilities as a legal means of payment.because there are still many countries that have not received bitcoin legally to use as payment received as paper money. and other reasons may still be many people who do not understand the bitcoin digital world....
You could say the same thing about gold coins, but I'm sure if I wanted to buy your hat off you for a handful of them you'd be more than happy to accept them as currency, right? You can't necessarily let governments be the deciding factor of what is currency and what's not.
But in some way in country that we life they could decide if we break law or not, so if they won't allow us using it we will be in some way breaking the law and we could just make problems, so i am waiting for future cause i believe that then it will be legal worldwide.
