I think it would have been safer to power off that computer immediately, reboot and load an OS from usb, and do a full hard disk scan on the main hard drive.

Even safer, don't run windows for crypto related stuff.

Because fuck the central banks, fuck the banks.

You need to install lndhub, it's on git and it's created by the same people from blue wallet. It does exactly that, creates an accounting system and when you create a lightning wallet in the app, it starts from 0 independently of how much you have in the node.

The games they are playing are most of them from thndr: bitcoin bounce, bitcoin bay, bitcoin snake, sarutobi. They are on the stacksats.how website.

What wallet did you use?

Nah, they are bigger (primary school). They spend a big amount of their time playing games, so at least they can earn some sats!

Sorry I hit enter accidentally, the story is in the first comment above.

Answering your other questions, I backed their qr code yes. But I believe in effect it's a custodial wallet and I'm their custodian, so if they ever lost their phones etc. the funds are still with me.

No in house store they can spend bitcoin at but next time they want to buy stuff like game coins (like roblox, minecraft, etc.) I will refer them to bitrefill and there they can spend their bitcion.

Sorry I hit enter accidentally, without giving me a chance to write the body of the post. I'll write below:

In the last week I went through the process of setting up a lightning node (all done manually on an Ubuntu vanilla install, no umbrel, no citadel).

I then got my kids the blue wallet app, and pointed it to the node (you can via the advanced settings).

Then I sent them some sats, and they love sending money to each other with the qr codes, etc. For the next few weeks I may give them a bit of their allowance in bitcoin.

They also started playing some of those games that reward you with sats, they get really excited when they get 5 sats or what not.

A great experience, I recommend it.
