Crypto Portfolio

This command line tool consumes coinmarketcap.com's API and produces small reports of your current holdings. The composition of your portfolio has to be specified in a json file.

{
   "assets" : [
      {
         "amount" : 0.75,
         "id" : "bitcoin"
      },
      {
         "amount" : 3.6,
         "id" : "ethereum"
      },
      {
         "amount" : 42,
         "id" : "dogecoin"
      }
   ]
}

You can then generate a report.

Telegram Bot

The repository also contains a small telegram bot which is written in python using the python-telegram-bot package. Follow the telegram documentation to create a new bot. The bot.py program reads the api token from a api.token file in the working directory. The bot only produces reports for users whose portfolio specification is available in the working directory as <user_id>.json.
