Sort of like gold I guess.
I have never figured out "lightning network", their "solution" for payments. (bitcoin payments are so impractical that they have a different, separate system to use for actual payments, that works completely differently.) Seems very convoluted. I need to pay a huge fee just to make a channel so I can receive anything? And there is something about liquidity? I implemented bitcoin stuff and still cannot figure lightning out.
bitcoin is mainly for buying it and looking at a chart.
