@dumptoshi @Cryptoholixx @Murfski_ My buddy bought some  last month. He's not technophobic but not a hobbyist either. Wants to use  payments on his site.
So far he knows keep pkeys offline, don't keep coins on exch, use a Nano.

He asked "how to turn on LN &amp; what's a  node" 
He should be ok, right?
