If you don't want to invest your earning rate is:
But you can also invest in an upgrade:
You may withdraw your earnings when you reach a minimum of LTC 0.01; that is...
... 0.01 LTC / (0.0000004 LTC / minutes) = 25,000 minutes
... 25,000 minutes / 60 = 417 hours
... 417 hours / 24 = 18 days
When you reach the minimum and claim your earnings, you may wait 15 days minimum until you recieve your LTCs:
As you can see, I myself tested LTCMiner and I am waiting for my payout since May 4th 2018, today it's May 19th 2018, so I am waiting for 15 days not haven't seen any payout yet.
If I recieve any LTCs I will write a comment to this article. You may post your earnings if you want so that we can see how long it takes until you get paid.
