I have both Beastkeeper (silver) and Wajas (WC), for trade for Sylestia gold. What is BK silver worth next to Sylestia coins?

I don't play either of those, so I can't give you an answer based on how people feel (which seems to be how currency rates are done here, but whatever.). However, if you can give me the USD cost of their premium currency and the non-premium currency cost of their premium currency, I can calculate what it should be according to the maths. (I'm a bit OCD about following the maths, so, I'm good at doing conversion rates. They are easy to me.)

Oh, thank you ^_^

BK Gold is $5.00 for 50g coins.
And I am waiting for a reply on my Beastkeeper thread...I have no idea what the in-site exchange rate is.

This link is for me to check back on:

Don't know the answer to your question (and am probably biased because I can make silver more easily on BK than Sylestia)
Just curious, whats your username on BK? Mine is the same as here.

So $5 USD = 50 BK Gold Coins = 500 Sylestia Diamonds

So 1 BK Gold Coin = 10 Sylestia Diamonds
1 Diamond (On average) = 3000 - 3500 Sylestia Gold.
1 BK Gold Coin = 30K - 35K Sylestia Gold

To get the rate of the non-premium currency, when you know how much 1 BK Gold coin goes for in the non-premium currency on Beast keeper, Divide 30K - 35K by that rate.

Note, some people say well -insert site name- is easier to get such and such currency on, but that's actually accounted for in the conversions. If say diamonds are hard to get diamonds will cost more gold because they are in higher demand.

Take Flight Rising compared to Sylestia for example. Diamonds are harder to get than Gems, so Gems cost less Treasure than Diamonds cost Gold. If Gems were harder to get, they'd be in higher demand and Treasure cost per Gem would be higher because there'd be fewer to go around. That would make the gap of the conversion rate shrink. So instead of being the 5 Gold to 1 Treasure it might 2 Gold to 1 treasure, or even reach 1:1. (I'll stop my little lesson on converting currencies here, since if I don't I might go into a rant about people arbitrarily plucking numbers to suit their needs instead following the math.. and no one likes rants.)

My BK username is the same as on here too :)

That is some very useful info, it makes total sense! I'll be referring back to your post in the future ^_^
