Building new logistics is already an important one, but another large part of it is risk aversion. For instance, it can be done either with or without collateral; too small an amount might not worth my time to handle, a large amount requires collateral. With collateral, I do not like the lost opportunity cost except with possibly BKS, which might not need to be liquidated in a few months.
The collateral also has to be smaller than 100% because of cold / hot wallet risk - handling liquid NBT or BTC is risker than keeping illiquid funds in cold storage. Even without collateral, losing funds will cost me the trust and reputation that earned me the uncollateralized custodianship to begin with, which we can assume is usually larger than the amount of the custodial grant. All in all, to me there is a gap between the potential risks and incentives, and I have not yet found an appropriate compensation level to adjust for that. Thereās also the fact that Iām not properly anonymous, so the risks are higher.
