I will be willing to answer any questions in the comments. If you would like to know the spelling for a particular coin look at the coin on coinmarketcap and click the tools tab to determine how it should be spelled for the API to properly return information.

Also, if you would like to see your portfolio in terms of ETH instead of BTC (Since some people think ETH is about to take over dominance), then just change every btc in the PowerShell script code to eth.
