I would love to see Bitcoin be the winning cryptocurrency but I fear that the lightning network is just too complicated. It seems impossible that Bitcoin is ever going to be the best currency in terms of technology, and really for anything to gain mass adoption it is going to HAVE to be (in my opinion) easier, faster and cheaper than the fiat system. Look at STEEM for example, the transactions are free and take just a couple of seconds, that is already better than the lightning network, and as everything occurs on chain it's simpler and more secure. Other coins like Stellar and Raiblocks also offer technology that is probably better than Bitcoin can ever be. Like I said I would love it to succeed, but it is really starting to look like Bebo or MySpace IMO.
