I think this will help so much in disputes. Currently when this happens the user has no way to prove to the public that the dispute is actually real and the exchange has done something wrong like hold funds. Its just your word vs the exchanges. Usually what ends up happening is users complain on forums and hope for the best. With our platform when a user feels the need to complain online he can prove that we are holding his funds, and prove were refusing to counter sign his request.
But when users generally complain about an exchange holding their funds, they do get support responses from the exchange and usually, it's either KYC or another account verification reasons. My point is, the multi-signature system can't enhance the way the exchanges operates. For instance, I'd like if an exchange doesn't introduce KYC policies when a high volume withdrawal is requested but do it when a user creates an account.
