Deception : 9000

In the favor of maintaining the trust of the community (lmao at this point), maybe, just.. just maybe fix this: https://imgur.com/a/LXUfKjV
You set the coin value first (because an ordinary person usually does things top to bottom) and then your coins wanted changed based on the value you entered in the bottom field? If you are not paying close enough attention and are fairly confident that you know how to type numbers to not bother checking back the upper field, you can easily void $22 because of this very intelligent automated system.

You could say that it's to fight automated methods but that's sweet sweet bullocks because if I wanted to, I'd train my macro to do it bottom to top and that'd be it. The only thing this accomplishes is to prey and literally SCAM people who don't pay close enough attention who couldn't have known that this automatic price change existed in the first place. Or if you wanna keep the automatic stuff, at least make it read up to down.

Edit: I even fixed it for you. Now monkey see - monkey do. https://imgur.com/a/YUPRnpi

There's no "scam," just a fully disclosed and well-known by many enforcement of minimum/maximum values, the same way that happens with characters (and leads to all the complains about "why can't I sell my character for half a coin?????"). If you try to sell a large amount of coins for too little gold - like your example of 25 coins for 45000 gold - the system simply enforces the bare minimum/maximum set by us.
