OBTC tracks bitcoin, but there are a few things to keep in mind when using this service. First, OBTC does not store any bitcoins itself. Instead, it uses an API to track the prices of various exchanges. This means that if an exchange goes offline, OBTC will not be able to track the prices of that exchange.
Secondly, OBTC only tracks the prices of bitcoin, and not of other digital currencies. This means that if you’re looking to track the prices of altcoins, you’ll need to use another service. Finally, while OBTC is a great way to track the prices of bitcoin, it is important to remember that it is not an official exchange. This means that the prices on OBTC should be used for informational purposes only, and not as a basis for trading.
