I think that I know what could get more people to play game.

If older members would have more motivation for spreading the word about site C:

I think there could be special rewards for more referrals, like more gold coins once you reach bigger number of recruited players or milestone rewards.

I would also suggest special skin/beast once you reach, lets say 100 reffered people.

And what about forum badges/titles like "Recruiter, Master Recruiter,..."

Thank you for considering C:

Like the idea of forum badges, but no to the special rewards thing.

With the numbers of referrals I've collected in my whole time on BK, I've collected probably around 1000 gold coins just from referrals. That's about 100 USD worth of gold already, almost effortlessly. I think that's reward enough?

The value of supposedly rare items is already dropping way lower than what it's supposed to be, so unless the prizes are small things like simple building materials, I don't really think it will work.

well im in the US and i think 100 dollars for a 1000 gold coins is CRA CRA

I mean u can buy a SELPHONE with a 100 dollars A WHOLE SELPHONE!

im not yelling im just saying if it goes to ur animal why in other places its like MUCH cheaper i mean i just take a vacation there buy it then go home then BOOM its cheaper i suggust they lower there prices i think 1000 computer game gold coins are worth 10.00$ well if they diliverd it i whould understand who agrees?

@Cheetah- Angel warned you about using about using Chatspeak in the forums. Things such as "ur" and "CRA CRA" are considered chatspeak. Plese spell out words and avoid using capitals unless necessary. Please double check your spelling for accuracy. Take this into consideration or it could lead to another warning.

The rate of conversion from USD to Gold coins is not all that different from other pet sites I play. These rates have a lot of thought put into them. It costs money to host a site. It is important that there is a balance between gold and USD. The site needs to maintain itself and gold coins still need to be "rare" enough for people to feel it is worth donating. I'm sure that there was a lot of thought given to this. 

Some sites give referral points instead of "premium" currency. I rather enjoy that BK has given people who don't have the oppertunity to donate the ability to get gold coins for referrals. Perhaps as the site moves on it may be worth it to give less gold coins or create a referral points system. This would help to not devalue the gold coin and encourage donations. If more donations are what is desired of course.
