Basically what you do is create a low level character and call it something like moneydraw. You could do it with your normal character but there is a way to make some more gold if you don't!
Once you have your character its time to get to work. Make a macro for this as it is a lot quicker and helps having no mistakes. Make the macro like this
/e Double your money quick!! roll above 75 to win
/e whisper me saying how much you want to play with
/e then trade me the money then you can roll!
/e If you get 75+ you get your money doubled
So you can walk around using the macro every so often and it gets people really interested! You can either do it legitimately or just take their money even if they win! I actually recommend not scamming people as no one will be shouting out OMG Moneydraw just scammed me!! Even if you take their money and make a new character people will still be nervous about playing if they know someone has been scammed. Have fun!
There are lots of other ways to do this, like with boxes wrapped in christmas paper, if they pick the box (of like 4 or 5) they get their money doubled or it costs money to play and they get to keep the green if they win
