Project for the weekend. New #meshtastic node using the Heltec T114. I’m interested to try this one as it uses the Nordic nRF52840 which has a lower power consumption than the ESP32 based boards so should have better battery life. It also has a colour display. I’ll probably end up 3D printing a different case for it but the one included in the kit will do for now. 
Discussion
What would be a greatest use case for meshtastic?
Why should one buy it?
I’m trying to figure this out and I’ve looked through the information and can’t find a strong use case for it.
Can it relate to bitcoin in anyway?
The biggest use case I can see for it is for communications in a disaster situation where power is out and phones/Internet are down. Meshtastic devices can keep running on battery power for long periods of time or powered from small solar panels so would be easy to keep operating.
It is low speed though so really limited to text only communications.
There are projects to send Bitcoin transactions over Meshtastic although they do need to connect to a Bitcoin node somewhere. Potentially useful for sending transactions from a location where an Internet connection is not available.
