- You probably need to have been active in the Bitcoin community for at least a year.
- You probably need a very high OTC rating.
- You need to have dealt with far more BTC at one time than what you'll be holding for the forum.
- The list of "treasurers" and how much money they're holding will be public.
- The contract will be quite complex (I haven't finished writing it yet), as this is the forum's money, not mine, so you'll have to know what "the forum" is and in exactly which circumstances you can release the money.
- Full reserve is not a requirement, but you will be responsible for returning the money within a few weeks of a legitimate request no matter what.
If you're interested, post here with how much you would charge for this service and what your reserve policy would be.
If you deposit 1000 BTC you get a[n extremely rare] free MPEx account, whatever gpg you wish to use for it (yours, forum's, w/e). You can either keep it in there (in which case it'll just sit around and wait) or trade on it, in which case your risks are whatever you make them.
Withdrawals are processed within 48 hours (tho usually it's instant if you ping MP).
