This demo script publishes a value to my Adafruit IO account once every minute or so from an Adafruit FONA 808 cellular board controlled by an Adafruit Metro and sending data over the Hologram network.

| # My attempt to understand inflation in the mineable cryptocurrency markets. | |
| # | |
| # Every day mineable coins (e.g., Bitcoin, Ethereum, Litecoin, and | |
| # Bitcoin Cash) add coins to their total market cap. Coins are produced by | |
| # mining, miners have real fiat bills, therefore miners have to convert coins | |
| # to fiat in order to continue mining. | |
| # | |
| # Selling new coins into the existing market means an equivalent amount of fiat | |
| # needs to be added in order to keep the price flat. NOTE: selling new coins | |
| # for fiat also requires real-currency markets to be available for exchange, |
