Everything is made faster and smother. The UI is a great improvement. You'' actually get more people into the crypto infrastructure. When I 1st got into crypto, the interfaces look terrible and I had to do some digging to find important information. I'm bit of a geek. SO I made through it.
But if we need true decentralization we need to get the random people to participate like how things are happening with P2P downloads. As for lightning network earnings.... I hear that ROI is very low. I'd stick with STEEM.
