The relationship between LTC and BTC is very interesting. LTC looks to be pumping over the last week or so and probably (IMO) headed higher, plus the LTC network difficulty is crashing right now.

I would conjecture that there may be some movement in CNY into LTC from BTC because of apprehension about what will happen to BTC value and/or the BTC network after the halving.

LTC mining looks set to become more profitable.
