I doubt the lightning network will make Bitcoin great again. I mean it's definitely a big step forward, but BTC will continue to lose dominance in the course of 2018. So many other cryptos have been created. Many of them have already proven its applicability to use cases like micropayments that I do not believe BTC will take this niche again as a dominant player.
Successful integration of lightning will definitely affect positively on BTC price but it will continue to move towards store of value use case (similar to gold) rather than a mean of payment.
