Don't expect this to have any positive effect on bitcoin prices. Most people not in the crypto community won't hear about it for months or possibly years. Most in the non-crypto world have yet even to hear of SegWit -- when Coinbase announced its own SegWit implementation, the community was dancing in the streets. And around the world the bitcoin price promptly crashed.
Are you serious? Segwit is being adopted widely by many users these days including myself since more and more people are recognizing the significance of this revolutionary technology and I am expecting it to go mainstream by the end of this year. The lightning network is something which many members of the crypto community have been waiting for anxiously and this will definitely help in triggering a bullish market and will spark a huge rally by the king of the crypto market and other popular altcoins like Ethereum, Ripple, Litecoin etc. This is my optimistic view regarding this feature.
