1) I never lend to neg-trusted members.
2) I accept only bitcointalk accounts as collateral, as they very easy to liquidate here.
3) I lend up to 70-80% of the account value, to prevent get scammed by account farmers.
4) Get a signed message. This is very important! I have been in a bad situation recently for not requesting a signed message.
No signed message = no loan
I have given loaned small amounts to a couple forum members before... and i follow similar rules to tsoPANos... Although i would accept altcoins, almost nobody that needs a small loan actually has any ALTs as collateral anyways... Maybe this is different for bigger loans, but i only loan 0.01 to 0.1 at a time
