Simple Python script that will show you the value of your portfolio in US dollars.
Uses the Kraken exchange to get prices by default but you can easily change this.
You will need ccxt, the library used to get cryptocurrency prices.
pip install ccxt
Create an accounts.yml file. (See accounts-example.yml as a starting point.)
To run the program, run python pyCryptolio.py
You can pull data from different exchanges by creating an exchange value in accounts.yml.
For example, to use bitfinex.com, put the following in accounts.yml.
exchange: 'bitfinex'
Go here for a list of exchanges. The name you would want to specify in accounts.yml is under the id column of the table on that page.
