My twitter and instagram means the world to me.
I could also give my xbox account which has the same balance with my life earnings on it. I can literally give anything that someone would request.
Even my Greendot login
For some reason I doubt that your life savings are stored on your xbox account, however even if they are then the balance would need to be transferred to the lender for the duration of the loan (I am fairly certain xbox balances are reversible so this would still not make good collateral).
greendot login is similarly worthless as the lender would need to have any balance whose value exceeds the value of the loan in order to properly secure the loan
