While we ponder on transparency, I would also want to know the mode of payment for the company because it seems we are concerned more about the safety of the clients and not considering the fact that, it’s a two way thing and as such the safety of the firm also needs to be taken to consideration because clients can be really funny at times And a typical way to balance this should approached.
Maybe the payment option could be from the agreement between the two parties, as they have signed because I see no reason why the wallet owner would pay money when the organization is in possession of the wallet with funds in it. If they had reached an agreement based on a percentage, it would be feasible for them to deduct the percentage as agreed from the wallet agreed rather than the owner sending them payment separately. Both parties would want to protect their interest, so I also believe the owner of the wallet would not want to pay anything outside of what they have agreed, coupled with the fact that they are already holding a wallet with funds belonging to the customer. This is just a thought of one being careful not to make any silly mistakes.
