What is the newBlockHeaders subscription for? #11

Closed bart closed 2 years ago

Hey, great work and an awesome post you wrote about this topic. Thanks a lot, appreciate it. While looking through your code I saw the subscription on newBlockHeaders event. What is this subscription actually for? Is it just used as a trigger for price monitoring? As far as I can see I could also be replaced by a simple while(true){} loop that sleeps for a couple of seconds every loop, correct? Or do I miss something here?
