📉 The bitcoin is falling, boss!
We will teach Python to monitor the cryptocurrency rate and notify if the rate is above or below the threshold.

We will create a function to get the BTC price in USD via the CoinGecko API:
Now — the main monitoring cycle. We will set a threshold and check the price every minute:
🔥 You can also easily adapt it for Ethereum, DOGE, or even Telegram Token — just replace bitcoin with the desired coin in the URL.

We will connect the
requests library and import time:import requests
import time
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)

We translate a text in a few lines using
deep-translator. It supports dozens of languages: from English and Russian to Japanese and Arabic.Install the library:
pip install deep-translator
Example of use:
from deep_translator import GoogleTranslator
text = "Hello, how are you?"
result = GoogleTranslator(source="ru", target="en").translate(text)
print("Original:", text)
print("Translation:", result)
Mass translation of a list:
texts = ["Hello", "What's your name?", "See you later"]
for t in texts:
print("→", GoogleTranslator(source="ru", target="es").translate(t))
