We will create a function to get the BTC price in USD via the CoinGecko API:
def get_btc_price():
url = "https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd"
r = requests.get(url)
return r.json()["bitcoin"]["usd"]
Now — the main monitoring cycle. We will set a threshold and check the price every minute:
threshold = 65000 # specify your goal
while True:
price = get_btc_price()
print(f"BTC: ${price}")
if price > threshold:
print("🚀 Time to sell!")
break
time.sleep(60)
🔥 You can also easily adapt it for Ethereum, DOGE, or even Telegram Token — just replace bitcoin with the desired coin in the URL.
