I started to download the blockchain and I noticed that my node never exceeds 10 peers.
There is some sort of limit on it? I have another node in my home and it has more than 30 peers connected.
If it is a limit, there is a way to edit it?
No, is by design like that (in special using Tor) when the node it hasn’t the port 8332/8333 exposed to WAN.
You don’t need more peers. Those peers are ONLY to sync the blockchain NOT for your LN node.
No worry is just fine with 10.
