You are a scammer and no, you didn't do the work. The developer did the work which you want to take credit for by compiling their work and distributing the executable, breaking the GPL license and screwing the developer out of his voluntary fee.
While I hear your point, I think 1% of ALL MINING CAPACITY OF THE ENTIRE WORLD is wayyy too much for someone who took a miner and modified it for a new algo. The 1% is like owning 100 x 7GPU mining rigs or something like that. The miner fee is OK but should be a lower reasonable amount.
In case of JUST XMR, the 1% Developer fee currently equates to over $110,000 PER WEEK with ZERO electricity cost. That is just ONE coin. No copy/modify/fork/paste software developer deserves that much unless they are Satoshi himself.
Xmr stak developers did not took a miner and modify it, they wrote it all from zero ground.
So they deserve the 1%.
No one writes anything from scratch. Its all copied over and over from existing GPL. 1300 Cryptos and there are 5 only ideas behind them. CGMiner may have been unique in its own way.
It's true nobody does anything from scratch. They either get ideas from somebody or copy here and there and to get something.
The latest DEV fee for XMR stak is 2%... These guys are forcing you to mine for them for using their software. Should be illegal but hey it's the land of the free.
