I did invest a little in KNC, but I feel it does not have very good potential. Only reason why I invested in the first place is due to VB.
I also feel it does not have good potential.
but Assuming KnC scrypt miner will be used for Litecoin mining, data from
https://bitcoinwisdom.com/litecoin/difficulty, and math skills so I try to make a calculation like what when 20.000 Mh / s hashing power is on the market. In my opinion

Coin has a "defense mechanism" to keep its speed in generating blocks (which in turn will "dig") always the same. Hardness level block (difficulty) is influenced by how quickly the speed of 2016 pieces block before it is issued.
After 2016 blocks generated, Litecoin will adjust the delay time of 150 seconds. (
