Does anyone of a way to receive a notification when a certain Bitcoin Address changes amount?

I want to see when the Bitcoin I found left on the mountaintop moves, but I don't want to have to check every day

To quicker Orange pill the world, we need more of a Bitcoin economy. Nostr connects buyers and sellers of services and products like never before. Here are a few businesses that can be started via Bitcoin Lightning. What else am I missing?

1. Fiverr type service (Bitcoin instead of fiat)

2. Merch on demand for designers (Bitcoin instead of fiat)

3. Craigslist type marketplace (Bitcoin instead of fiat)

4. Bitcoin financial planners

5. Bitcoin endowments

6. Fitness coaching paid by Bitcoin
