Once LN is fully implemented and if it proves to lower fees and transaction time then you will see BitCoin really take off. The only thing that will hinder its growth will be the constant FUD from possible bans by governments and regulators. 2018 looks like a good year for BTC.
Every year is a good year for btc because it keeps increasing, yes constant fud affects the price of btc but it's only temporary and btc price will continue to rise. Now it's getting more stable. I am expecting that btc price in continue to rise after february. I hope whales will gonna pump again the btc.
