The narrative "run your own lightning-node" is for the average user not feasible. Even misleading.
On a LN-node, maintained by the average user, without hours, days and weeks of bothering, and charging the channels with several millions sats, tx simply do not go through, no matter how large, be it 200 sats or 2.000.0000 sats.
That´s the simple diagnosis after 6- 7 years of LN. unfortunately.
that´s not an ad.
