Thank you, but I have a few problems:

1- I live in Iran and am under US sanctions, so most LSPs do not serve me.

2- WireGuard is blocked in Iran, but OpenVPN is open.

3- I do not have enough sats to open a channel.

4- I am not a newbie, I have been a Linux user since 2007, and setting up a Linux VPS is easy for me, but I am too old to bother with documentations and codes. So I think using a custodial LN provider is more suitable for me.
