im not sure what you mean. as said its likely to happen that people use simply their whole money on someone they hope for. Severeal people doing that, all have the same amount of Hirams, what is the solution? also you dont seem to be aware that alot of people wont care if their avas are logged in your system, this will be a dom-only problem rather and i doubt youre interested in single-case solutions each time at the start of the auction. you need a system where you dont have to worry about slaves are not interested in more than one times of trying this out because that will be the case often probably. trusting on a "market" system is hopeless aslong people are not really forced to getting sold. its a rp-fantasy and nothing more. i see the highest chances for this working out with using gifts as currency actually. its also the easiest for you. let the buyers pay the house or the former owner of the slaves in gifts and you have a really betting system. one gift of money = 250 hirams or something like that
