In my opinion, BTC is not a traditional currency like gold and silver because it does not have any use value, so it is not a credit currency. It's basically just one use, money laundering tool. The tool explains why bitcoin prices are spread across the country and abroad. Domestic money is changed into bitcoins and then physical transportation to overseas exchange for foreign currency escapes regulation and the cost of money laundering is lower than before, and the risk is low.
At this time btc is considered a kind of money laundering tool and deals with low cost but I think in the future if more people use btc then it will become an official currency that will be more who accepts as well as use to trade officially without cash exchange anymore
