For example i have 2 BTCs in my bitstamp account. am i going to take a screenshot?
just little confused, if you have 2btc , that why you need loan? unless you account suspended and fund not withdrawable.
in that case it worthless as collateral
Ergo he has to use an old screen-shot or a skewed perspective screenshot of his bitstamp account in order to provide "collateral" .
This collateral is like showing a thirsty person in the dessert a picture of a water bottle and telling them you promise you have water, but all you can show is the picture.
