How can I get Bitcoin price to show on watch face

Salutations bob from laguna niguel,

If you currently use a third-party app to track this data, you’ll want to see if they offer a complication for watchOS. This would then show on supported Apple Watch faces and you could see it there. 

If you’re tracking it using the Stocks app, you can use the Siri watch face to show a stock complication and try it there. 

1. Open the Settings app on your Apple Watch.
2. Go to Stocks > Selected Stock, then choose a stock.

Additionally, this article goes over all the watch faces and the available complications for built-in iOS/watchOS apps - Apple Watch faces and their features

Thanks.
