My current KHS are from faucets as well. I had ordered my first 2 BTC the same day I signed up (3 days ago). I am waiting for them to come in my Coinbase so I can send some to my scrypt...
I am wandering though: Would the 10 min pay out drop if I do not keep reinvesting my BTC in KHS?
Mining rewards are actually supposed to change in a radical manner, in value and in time of appearance. This applies to HashNest, for example. But on Scrypt.CC rewards are strong and steady, every 10 minutes the payout only depends on the KHS you currently hold. If you don't reinvest it won't drop, but it won't grow either. There are some tiny highs and lows / delays now and then, but they are steady and very punctual 99% of the time.
This is not advertisement, since I cannot explain how they manage to do it without going the Ponzi route. What is nice is that if you reinvest, you will not only be making more BTC to hold expecting it to gain value, KHS itself floats in value. This can backfire, of course, but in 6 days I made 6% profit only selling KHS, not taking mining into account!
Are you sure the payout/KHS does not drop?
The reason I ask, is that if I kept re-investing my BTC into KHS (growing) and until I reach a certain amount of KHS and then decided to just cash out the BTC revenues per 10 mins, would these BTC remain steady? Wouldn't they revenues just start to drop after a while as difficulty increases like all physical miners?
My concern is that the only thing keeping my generated BTC per 10 minutes revenues at the current rate is that I keep re-investing... The problem is I can't see much difference because I am currently working with only 468 KHS, I do however see some fluctuations in my satoshi revenues between the 10 min intervals...
