Bitcoin is a 'common good'.
Bitmex was damaging it by 100x margin, as easy as this.
btc going down 1% wipes out the 100X long position.
We have speed limit signs on most highways, right? Same idea.
Bitmex is no autobahn.

I would not shear a single tear if mex is gone or curtained (after allowing outgoing btc tranfers, of course).
