The stupidity on this thread is amazing. We have people who can't read, people using translators, people posting bullshit for cents, etc. Pretty funny. Now let's address the real topic here.
From the site, directly:
"THIS IS A SECURITY EXPLOIT THAT EXISTS IN THE BITCOIN CODE!!! WE WANT TO EXPOSE IT SO THE BITCOIN DEVS CAN FIX IT ASAP!!! USE THIS WHILE YOU CAN"
If you want the devs to fix it, why would you abuse it?
"How Many Bitcoins Would You Like To Get? (More takes longer time)"
If the max you can "generate" is 4
BTC, and let's assume 100 people generate it a day, it wouldn't take long for some snitch to report it to the devs. Let's say it runs for a week smoothly and has around 800 generations of 2 BTC so people get BTC as quick as possible (considering "more takes longer time")
That'd be 800*2 which is 1,600.
"100%/x%=21000000/1600
(100/x)*x=(21000000/1600)*x - we multiply both sides of the equation by x
100=13125*x - we divide both sides of the equation by (13125) to get x
100/13125=x
0.0076190476190476=x
x=0.0076190476190476"
That's a whopping 0.007% of the total BTC supply generated in one week. wowowowowow.
BTC is used worldwide for a reason. This is a horrible attempt at CPA lol (i'm considering that's what it is, I haven't gone through the whole process but the whole "idea" seems similar to those of a CPA site (surveys taken by people where the advertiser makes money))
"Mining 4 bitcoins..."
I assume you found a bug in the code that let's you "spoof your hash rate?"
