Hello, first thing to say is that I am brand new to running Umbrel and a Bitcoin node on a Raspberry Pi 4.
I finally managed to connect my Sparrow wallet after stumbling on the fact that I had to install Elects. I have a blue button in the Sparrow confirming that it is connected to my private electrum server and have sent and received a few sats!!! (Major victory, I almost gave up and used a Public server)
This brings me to a question or two:
What happens to my bitcoin if my Pi setup gets stolen? I do know that the BTC is on the blockchain, but how would I access it without the Pi and my node?
My son tells me that it is dangerous to run a node and opens my network as a potential target. I’ve never really worried about this before, I run Norton and always use a VPN, Tor is new to me. How do best I protect my network? And what exactly makes Umbrel secure?
Please excuse the very basic questions, I’ve not found a straightforward answer from hundreds of searches and I hoped that someone here could explain to me like I’m 5.
