No, absolutely not! While some of the largest cryptocurrency exchanges are situated in the United States (for example, KuCoin or Kraken), there are other industry giants located all over the world. Binance, for example, is situated in Tokyo, Japan, whereas Bittrex is based in Liechtenstein. While there are several reasons why an exchange might choose to be situated in one area over another, the most of them are commercial details that have no bearing on the platform's user.
