It think the surge of LTC is not related to BTC and its the other way around. Or if there is a correlation between the two then it might be just small range in price that will be evident.
The Chinese I guess will make things possible for this coin and it will affects Bitcoin in some points, knowing that btc is the major crypto being used inside the exchange if investors will bring LTC to it's hype mostly they will use Bitcoin as a base currency, though there's also some pairs around but mostly Bitcoin will be bought before exchange it to LTC for investment process.
