Hi folks.

I registered because of your post, the last answers and really I read it 10x times - I didn´t get it.
Hope my english is not to worse. 

Lifetime is lifetime, but ..
1. There are maintaince fee´s. OK, got it.
2. If you didnt get enough BTC because of reward down from 25 to 12,5 or new machines are on the market mining more efficient then your fees can get higher then your income. Got it.

If I buy 100MH/s (for ex.) today with a fee of 1mBTC (just example prices!)
And another 100MH/s in 90 days with a fee of 0.5mBTC (because network has a new 10TH/s miner for just USD 300,-  )

... what will happen with my upgrade.
Is it 200MH/s with 0.5mB fee or is it a mix and 0.75mB fee.
OR MORE BAD is it 200MH/s but with the old fee of 1mB (in this case it would be smart to do a new account before every upgrade after a time or after fee is set higher)

And, well ... fee up - fee down ... where can I see the today fee`s? The yesterday fee`s? 
I got the tomorrow fee`s for you if you donate me 1BTC  (1000% cashout --- cannot read this shi...ning words anylonger) --- back to topic.

Will the fee´s always stay the same for 1 MH/s?
I would answers YES because some years ago you were the king with 50MH/s - then with 1 GH/s ----- 4.73 TH/s with Ant-S7 now is standard (shocking) -----
And I could bet - the No. 1 can always get the No. 2 or 3 again, if someone else is really smart (so not me, but somebody) 

So please give me a short hint WHERE I can see the fee before buying.
And what is happening while updating / upgrading your GH/s contract with your fee´s. (Old, Mix or new)

Example is for GM for the Lifetime only. (not for X11 or ETH - anyways gpu-mining and they have no lifetime)

Thank you in advanced if you have any ideas.
