I'm regenerating as fast as anyone, but still only had 11 gold, starting from the first 5 minutes after event launch until now. That's a little worse than before. I don't remember the cost, but I have gotten both the SSR weapon and eidolon and have 19 silver remaining. I believe that puts me at 44 silver, which is about 17.4 per day.
Whatever luck you have, I want in!
