It grabs BTC price, calculates time left, and posts updates to Nostr relays using the nostril CLI. This script also calculates the price difference needed for Balajis to win the bet, computes the multiplier, formats the remaining time message, and sets intervals for the next price check, all while continuously looping until the bet's end date.
