Not by anyone serious. Sure, people get liquidated all the time because they don't have enough maintenance margin. The risks are very clearly defined, and all you have to do is read them.
> When every player is operating in bad faith it is very hard to come up with a legitimate way to protect yourself other than not participating.
There is no evidence that the major exchanges are operating in bad faith. And even if they were, what is your point? My point is that they could have neutralized the currency risk of their assets. And that point is absolutely true.
