Simple app that:

- gets and displays cryptocurrency prices from CoinbasePro for 3 major coins
- lets you add/subtract cryptocurrency amount and US dollars spent/gained, but doesn't rollback, all the input/reset is final
- calculates the total value lost or gained based on the overall money spent vs the current value of the cryptocurrency
- resets transaction values back to zero
- automatically logs you in as anonymous user, all data is linked to your device id.
