Well, in my opinion, it is better for you to mine yourself, take this example: you buy an antminer from bitmain at a cost of 41 litecoins + delivery and PSU... then you hook it up a pool and mine, considering that the antminer L3+ has 504 Mh/s and consumes 800 watts... even though price of litecoin fell... looking at this statistics... here is the profitability:

Bare in mind that my electricity is 0.19 USD/kWh
