(i laugh when someone asks how to support bitcoin and replies try to promote another network(facepalm))
running a lightning node is not about bitcoin. dont let people fool you. its a different network and a risky network, where many people lose their funds. (even lightning devs have lost their own funds using it, and they are suppose to be the experts)

also if you dont have much funds then when you lock up your value and then allow others to route through you, you may end up spending more of your value to re-balance yourself after people use you as a route,
the small fee's you get for offering your balance may not offer you profit compared to the cost to re-route your funds in another longer(expensive) path to rebalance your channel(s), or the cost to open and close the channel.. so do research and dont be lulled into some fake promotions where people pretend lightning is the better profitable network

the lightning network does not help contribute to bitcoin. it infact is the agenda of causing people to use bitcoin less because they are being forced away from using bitcoin and instead told to use the lightning network. so dont be fooled by all the shenanigans of the subnetwork support group trying to promote another network as "bitcoin"
