Also note that I don't know of any ISPs who have a no-bitcoin software policy and aren't going to kick you off their network for relaying Core traffic. That would be the only scenario in which you must use Tor.

Most ISPs however do have a fair-use policy which limits you to download certain amount of data, and running your node behind Tor won't circumvent that.

The Core devs did a much better job at selecting trustworthy DNS seeds to download peers lists from (which is the only thing most of seeders do) than we ever could.

In this article https://curiosityoverflow.xyz/posts/bitcoin-electrum-wallet/ i found out that Bitcoin full node IDB should be done after changing bitcoin-core configuration to run over Tor.
Not necessarily.
Does it really matter, do i ruin privacy if i download full node without Tor? If its really matters, will it work if i uninstall then do reinstall and setup bitcoin core to run over Tor and download prune node instead of full node, since for EPS prune works as well ( my goal is to set up Core to run over Tor and use Electrum with EPS in order to use Trezor) Huh?
Well, yes. Since you're running it on clearnet, whoever is monitoring your traffic (ISPs) would be aware that you're using Bitcoin. However, this doesn't necessarily leak any privacy as nothing sensitive is transferred over clearnet during IBD. Pruned mode or not, it'll download and verify all the blocks. There is no difference in the time taken. If you absolutely need privacy, I'll rather just run it through Tor.

Can you please give your opinion on this too? Is this step necessary for privacy, if yes can you please tell any secure source where i can find those nodes? The article gives several nodes but i rather use nodes found from some legitimate source.
No. It is far more dangerous for you to specify a preference of nodes for the client to connect. There is no reason why you should trust us, or any website to provide you with a list of non-malicious nodes. DNS seeds are used only when necessary and Bitcoin Core already attempts to diversify the nodes that the client connects to. Bitcoin Core does have countermeasures and should provide sufficient privacy unless you're ONLY connected to malicious nodes which is quite unlikely.

1st Question
In this article https://curiosityoverflow.xyz/posts/bitcoin-electrum-wallet/ i found out that Bitcoin full node IDB should be done after changing bitcoin-core configuration to run over Tor.

2nd Question. In the same article it says :

Quote
Bitcoin Core will still query for peer addresses via DNS lookup # if low on addresses these 2 options disable this functionality.
dns=0
dnsseed=0

Since we have dns=0 and dnsseed=0, we have to start with some nodes that we can sync from (you can use your own nodes that you can find online.

Can you please give your opinion on this too? Is this step necessary for privacy, if yes can you please tell any secure source where i can find those nodes? The article gives several nodes but i rather use nodes found from some legitimate source.
