That's positive news, but still not enough to cheer the market back up. I don't want to sound negative but even when Lightening Network is fully implemented, it'll be too late for bitcoin to win all the investors who already moved to support new cryptos. New cryptos are implementing features that are missing from bitcoin such as anonymity and private transactions. Bitcoin is already outdated. I'm not saying that bitcoin will die. I'm sure bitcoin will stay forever however, it'll slow down gradually until another coin takes its place as the main crypto-currency.
