This is a simple coin ticker that connects to api.kraken.com to get the trade data. This is a public api so no account at kraken.com is needed.
Included is the public SSL key cypher block so the connection is secure until the SSL certificate becomes invalid.
The certificate will become invalid at august 5 2022, 1:59:59 AM GMT+2.
The program will not run with less than 1MB PSRAM.
Set Tools->Core Debug Level to info to see messages and errors on the serial port.
