Pi 4 Bitcoin Node + LN Node

Hello everybody,Long time holder first time poster. I just set up a Full node with LN node on a Pi 4. Following this guide [http://bit.ly/2S9kibf] super easy, barely an inconvenience. Anyway, I'm not going to sugarcoat it I'm a noob and I'm hoping for some help.​First can you guys point me to any resources that break it down crayon Barney style for the slower LN bitcoin user?Second if I can ask a few questions in this post:LN QuestionsI deposited 89398 sats to my LN node. my total balance is 34708 sats. With the difference being tied up in the channel. Do you recover those funds if the channel is closed? Can you open more channels? How do I make my node fee less? Does the node just take a percentage of the deposited coins to open channels?Bitcoin Node QuestionsDoes the node require upkeep? It helps the network to just run a node correct?​Thank you for taking the time to read this and answer any questions you can. Like I said I've been a holder but the longer this goes on and the more money the government just randomly prints I'm seeing this as way more than just an investment. I see it as the future so I'm trying to learn as much as I can now.https://i.redd.it/12pbi7zs8u831.jpg​Respectfully,​noob via /r/Bitcoin http://bit.ly/2L35zxy
