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.
that's not true, since bitcoin and other cryptocurrencies are based on the blockchain technology, that is decentralizes and anonymous transaction, not all users are considered as laundering money, if we are to choose to cover our money anonymously, that is our right, it is our money, if it ought to be used for money laundering, still the persons who are involved in that act can be identified, before we can convert it to fiats, there are crucial requirements of exchanges for their clients that wishes to use their exchanges, they follow the law on KYC, bitcoin has more deep application to further make us earn from its opportunities to offer, not just money laundering.
