I understand that you want to get paid for youre work.
And if everything works, Good job.
Just be transparant. everything needs to be clear.
No hidding things, deleting things, answer questions like a proffesional.
And take let's say.. 10%
And give the other 10% to youre miners.
I can ensure you, You will get more miners and earn the same.
Edit: 10% is still allot if you ask me.
But...
it is good for a multipool!
hmm it's good for groestl holders.
You need to buy grs because payouts on youre multipool are btc / grs.
so value of grs goes up. And because youre a dev, you have a big bag of grs. so everything is on youre profit side.
More than half of multipool miners get BTC as payouts, not GRS.
As for GRS - yes, it's good for GRS.
And no, I don't have a big bag of GRS. But I have enough and I bought them myself for around 400-500 satoshi on mintpal and poloniex a few months ago.
I did not get them for free, like the 5% that DMD devs get or AidBit. And I did not get them from premine.
I posted even long time ago, that I see GRS price at 700 satoshi or even more. I tried to hold the price previously, but could not.
So it went down into 100+ satoshi range.
Now I have means to hold the price. And I am going to move it to 500 or even to 700-1000.
Wanna get some profit? Buy GRS now and sell in 1 month or 2 weeks.
The price has already risen from 105 to 180.
PS: Not sure if you know, but I am also paying out 10% of grs fee to support Groestlcoin.
