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 1m
BTC (just example prices!)
And another 100MH/s in 90 days with a fee of 0.5m
BTC (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 1
BTC

(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.
For the current Fees on the Hashrate you are purchasing you have to get to the upgrade hashpower than go to checkout, than select View Agreement Toward the bottom of the page and it will tell you the Fees.
To view your fees on older Hashrate you can go to your My Account link and in the drop down list go to My Orders and than you scroll down to find your Orders and you can View each individual contract which should tell you what Fee was attached to the old hashrate you have.
As far as the actual Fees go. Basically the old Hashrate will always be at the set fee they where when you bought it. If say a new Miner with better fees comes out and you go ahead and buy that, the new Hashrate will be at the new Fee Rate. So it would be a mix than, your old Hashrate will be at the higher rate, the newer hashrate would be at the new rate. So for instance say you buy 100 GH/s now at 0.006 for Fees, than later on a new one comes out and the fee for 100 GH/s would be 0.0001, the old hashrate will still be .006 but the new would be .0001.
You can view the Contract Agreement before the Purchase but you do need to add it to the Cart before you can actually see what Fee is included on the Hashrate your trying to buy.
Hope that helped clear up any questions you had about that.
