If we consider the risk associated with using a centralized exchange in performing escrow for our transactions and eventually they got hacked or went bankrupt obviously we have nothing to do about it because we cannot fight them back to recovering the lost funds, but in case of the campaign managers and their hiring companies this has to be an agreement they would have cone into symphony with before engaging on the deal of contract, with the recent happening i think others will learn and review or recheck their contract terms with the kind of managers they employed, but i think experience also matters here, it's not all about hiring a manager but those that can delivere upto task and has been here on the forum in charge of more than four signature campaigns over years and nothing got mixed up.
