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.
I think people have a different opinion, when we say bitcoin is a washing tool, that's also possible, because bitcoin can be used for some pusposes but it depends on the people about how they act and use bitcoin. Many different issues about bitcoin are used for any bad action, but there is no evidence to prove that is true. That's in my opinion.
