It will be great for us, we can easily buy everything and we can used btc in any countries, but it won't be too good for the country, the government need to arrange well so there is no tax evasion, and it also need to be controlled so crypto usage cant caused another inflation to the country, the best way to settle this one is to set up regulations
It will be a great thing to happened once Bitcoin is accepted globally, If the global financial market accepted Bitcoin as mainstream currency then the issue on Regulation is already address, the benefit we see now is an indicator that the future of crypto currency trading is more acceptable to the growing investors coming in the trading market. i am looking forward that the Digital Ages is the thing in the future market trading.
