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 Bitcoin is already outdated.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.
This really is not true. Various features / options can be implemented in the basic code, such as what we call for convenience "Bitcoin Core." Or it's equivalent for alt coins.
But the presence or absence of those features has no relation to what features may be put on another layer. And that 2nd or even 3rd layer is required for exponential network growth.
For example, can you conceive of a layer on top of bitcoin in which fully anonymous transactions were possible? There'd be a point of exit from the blockchain and a point of entry back to it, and that's all the info that would be available.
What this means is that "features" in an alt coin does not imply it is "more advanced or superior" to bitcoin. Not in the least.
