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.
It seems to me that you have limited thinking and you know very little about Bitcoin and its blockchain technology. There are a lot of discussions on this topic and everyone has their own opinion, but personally I think that money can be laundered in absolutely different ways and people did it before creating Bitcoin.
