so best choice is Signature campaign ?
any other way to earn free bitcoin ?
how if all of member bitcointalk use signature campaign

selling buying account and lending are the only other choice, but they come with a higher risk than signature, and they are probably less remunerative
i have idea to give loan if my rank Hero member
i will use bitcointalk acc to collateral
than if he not paid i will sell her acc
and i get profit from it
you don't need to wait to be Hero member to start giving loans.
you can do it right now. it goes like this:
you check the person who is asking for loan and if he checks out.
you ask them to send the collateral to a trusted Escrow
then you give the loan to them if they can provide legitimate collateral
if i use trusted escrow it will increase the cost of the transaction because not everyone is willing to transact with the free escrow
