Your node, your rules. And your node doesn't have to be online 24/7 (unless you plan to run a lightning node on top of the bitcoin node). I run my node on a VM as guest of a work-horse desktop PC (which is actually online most of the time anyway).
The real benefits come when you transact with your node and you connect your wallets to it, it gives you better privacy.
I'm not a big fan of that raspberry pi cheap hardware crap and ecosystem. Better use a old laptop and a ubuntu LTS OS and keep it updated.
I agree with everything except for the Ubuntu part. I rather use a lighter Linux distribution that takes freedom and security seriously, or better yet, use NetBSD or OpenBSD instead.

I‘m using debian without all this GUI crap. Should be also fine, shouldn’t it?
reply
Not for me, really. I used Debian for 23 or 24 years, until they decided to to stop giving me the freedom to chose components and go with systemd.
I upgraded from Debian ascii to Devuan ascii and have been using Devuan in servers, desktops, and laptops since then.

Cool, I will look into it.

If you already like Debian, you'll certainly like Devuan, since it is actually the continuation of Debian but without systemd.
I currently run a prune BTC node and a full LTC node on a Pentium 4 desktop with 6GB RAM and two 512GB HDDs on BTRFS RAID-1 on Devuan chimaera. I got all the hardware for free, and it works very well.
I want to run a full node on this box (I do in others). so I'm planning to replace the HDDs with 1TB ones and rescan the BTC blockchain. :-)
reply
Totally noob question: Does the node really have to run 24/7? What happens if I do some transactions, the switch it off and switch on in a few days?
I will still be able to do more transactions but only after it has synched the blockchain?
Also, are there special network security measures to undertake before running such a node? I mean Ethernet/WiFi settings, firewalls, etc.
reply
In order for other peers to connect to your node, you should run behind tor as this allows inbound connections. But most "batteries inlcuded" nodes do that anyway. Run umbrel (I'm using citadel, a FOSS clone) together with electrum server and you're ready to go. Wallets can connect via onion address to your electrum server. You don't need to open any port on your router for you home network.

Thank you! This is a good point. Also good that the node doesn’t have to be online all the time (not planning to use lightning).
As for raspberry stuff, they claim it’s a „cheap“ piece of hardware, but I just checked the prices on amazon and it’s >$150. Insane.
