This flow was submitted before accounts existed, so nobody owns it yet. If you submitted it, open the edit link you were given — it still works — and you can attach the flow to an account from there. There is no deadline, and attaching it retires the link for good.

Description
This nodered flow will get the bitcoin price in USD from the coingecko API and shows it on your awtrix light matrix.
Settings
- Modify the MQTT broker (Server) in MQTT Out Node: awtrix/custom/bitcoin
- Keep the inject node around 10 minutes to not trigger the API limit from coingecko.
- It is possible to change the currency from USD to another currency by editing the change node in the flow. Modify the msg.currency value. All possible currencies can be found here
Profit?!
