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.
Bitcoin has many different uses and it serves a variety of purposes. Of course, big criminals must make use of this technology to thrive. That is something we can not avoid. I always wait for the SEC's involvement, I hope the SEC will clarify things to make the market better.
