Why difficulty went 5x up ?
because the Multi pools are throwing 120-200 Ghash at the coin
this is ok cause large number of people obtained significant % of the coin supply in the beginning, reward structure was calculated very well
one still could mine couple of thousands by renting if you willing to spend BTC, seeing mining gear now between 200 and 800 MHS probably rentals they draw couple of thousands of LTCD a day and going against time table because 1/2 reward will happen not far from Today
a bit of advice.. burry LTCD wallet deep underground and triple encrypt with AES 512 or AES 1024 even if you have 1K of them

why do u think just 1k of ltcd will be worth that much? i hold plenty myself
because I am hoping for this
https://bitcoinwisdom.com/litecoin/difficulty (click on YTD chart) only achievable if there is sustained interest, Litecoin won't experiment with anon or neither they care for much from our list like tor, so there are key differences, so right now 1K LTC is like what 11 BTC I think, and ain't stopping, actually it is a bargain price. good time to purchase LTC (impossible to mine) I am not cause I enter coins in early stage via hardware (no FIAT), because I see parallels here and + of course
one of ideas that would add to HPS (hash rate per second) and value would be idea of "merged mining" look what it has done to peseta and doge coin both received boost, merged mining with LTC might be possible too although a bit funny but...
merged mining with darkcoin would seriously catapult this to Saturn, but they won't allow it, merge mining "dark variety" is not yet happening it does not have too DARK stands on its own (also impossible to mine and its difficulty holds steady, also bargain in my opinion but I missed it at the early stage.. my loss...)
