And while Bitcoin has been trending sideways, Litecoin has finally jumped over 50 dollars per coin (and made an ATH at slightly above 55 dollars at Bitfinex). It could be interpreted in the way that it receives some liquidity which continues to escape from Bitcoin.
In my opinion, Litecoin seems to be a "hedge" for people that don't believe that around August 1 everything will end well, and that's why it lost much less than other altcoins in the recent altcoin crash. As Litecoin has already activated Segwit, it has the same public that could potentially love Bitcoin's planned Lightning Network, so it could receive support from people from the "Core fraction".
The other altcoins have completely decoupled of Bitcoin, having lost 50, 60 or even more % with respect to their ATH. Bitcoin is still surprisingly stable, although it lost a bit these days, and I think it is the same reason I keep citing: people don't want to miss the possible Segwit bubble after August 1 if everything goes well.
It is not just "your opinion"
It seems to be what can be loosely interpreted as an established fact of sorts (at least, as much as such things can be firmly established at all). It could be possible also that Litecoin's price is resilient specifically due to other altcoins crashing, i.e. people are liquidating their stashes and moving their wealth to Litecoin (so it can be mostly altcoins' internal business, so to speak). Bitcoin is too big (to fail), and even if small fraction of liquidity that leaves it ends up with Litecoin, we will see an insane rise in Litecoin's price. But we are not there yet, and most people withdrawing their capital from Bitcoin are likely parking it right in the US dollar as of yet
