what do u think my friends as btc is a digital currency will it replace real currency and become the largest used currency.
I do not thing Bitcoin will replace entire fiat national currencies such as dollar or euro, but it can serve as an alternative economy to the otherwise collapsing and scammy fiat violence issued money.
It could be possible, there is a very small chance. The government will not want to relinquish control over real currency so easily. Although the level of popularity on a global scale could pressurize the authorities to give BTC an equal value to real currency too.
