If you going to beg for donations...
The minimum you could do...
Is putting up some numbers...
Show me your calculations...
Price of rig...
Expected Mhashes...
Future bitcoin value...
Future difficulty level...
Or do you just want free money...
Not even willing to spend an hour...
Putting up some estimates...
To back your lofty dreams....
What's with all the ...s?
As per request I will update my first post with some targets.
I plan to upgrade completely depending on the volume of donations received.
This could mean a 6970 to replace my 4850,
then if things keep going well I'll buy some other mining card,
put it in my old desktop and run that 24/7 too.
(My 4850 would sit in that after my first upgrade.)
Or maybe I'll crossfire, who knows.
Point is, all donations will go ONLY towards my mining capabilities.
All will be refunded +20% chronologically.
I think you would be better off finding friends to donate to you OP. The chances of you getting enough backing from here as an anonymous person with no reputation on the forum are slim. Maybe you can convince your parents, people at your university etc. to invest in you. They might not fully understand the cause as much as people on here do, but you'll get more money out of them.
Just make sure that you've worked it out properly and you can indeed pay these people back, because if you can't afford to do it on your own at the moment then I'm sure that you won't able to afford to pay them back if things go wrong.
