Crypto Status Bot

Linux Mint has a taskbar applet that keeps track of crypto investments, allowing me to keep track of the price of Doge from the corner of my eye. This is fine for what it is, but it’s clearly not informative enough. So I wrote a bot that pings my crypto portfolio into a Slack channel every morning. It goes a little something like this:

crypto_bot.py

import requests
import json
from urllib import request
from slack_lib import send_message_to_slack

def get_crypto_data(cryptos):
    url = "https://api.coingecko.com/api/v3/simple/price"
    params = {
        "ids": ",".join(cryptos),
        "vs_currencies": "usd",
        "include_24hr_change": "true"
    }
    response = requests.get(url, params=params)
    #print("API Response Status Code:", response.status_code)
    #print("API Response Content:", response.content)
    if response.status_code == 200:
        return response.json()
    else:
        return None

def format_price(crypto, price):
    if crypto in ["bitcoin", "ethereum","stellar","xrp"]:
        return f"${price:,.2f}"
    elif crypto == "dogecoin":
        return f"${price:.3f}"
    elif crypto == "shiba-inu":
        return f"${price:.6f}"

def main():
    cryptos = ["bitcoin", "ethereum", "dogecoin", "shiba-inu", "stellar"]
    quantities = {
        "bitcoin": 234,
        "ethereum": 234,
        "dogecoin": 234,
        "shiba-inu": 234,
        "stellar": 234
        "xrp": 234                  # note: coingecko doesn't have xrp via API
    }
    average_purchase_prices = {
        "bitcoin": 123,
        "ethereum": 123,
        "dogecoin": 123,
        "shiba-inu": 123,
        "stellar": 123
        "xrp": 123                  # note: coingecko doesn't have xrp via API
    }

    crypto_data = get_crypto_data(cryptos)
    if crypto_data:
        total_current_value = 0
        total_initial_value = 0
        total_percent_change = 0
        total_value_change = 0
        output = ""
        for crypto in cryptos:
            price = crypto_data[crypto]['usd']
            percent_change = crypto_data[crypto]['usd_24h_change']
            current_value = price * quantities[crypto]
            initial_value = current_value / (1 + percent_change / 100)
            value_change = current_value - initial_value
            total_current_value += current_value
            total_initial_value += initial_value
            total_percent_change += percent_change
            total_value_change += value_change

            # Calculate delta
            average_purchase_price = average_purchase_prices[crypto]
            purchase_value = average_purchase_price * quantities[crypto]
            delta = current_value - purchase_value
            delta_percent = (delta / purchase_value) * 100

            formatted_price = format_price(crypto, price)
            output += (f"> *{crypto.capitalize()}:*  {percent_change:.2f}%   {formatted_price}   |   T: ${current_value:,.2f}   D: ${delta:,.2f}  ({delta_percent:.1f}%)\n")

        overall_percent_change = ((total_current_value - total_initial_value) / total_initial_value) * 100
#        output += f"> *Total:  {overall_percent_change:.2f}%   T: ${total_current_value:,.2f}*"

        send_message_to_slack(output, username = "🪙 Crypto Bot 💱")
        #print(output)
    else:
        print("Failed to retrieve data.")

if __name__ == "__main__":
    main()
