This is such bullshit.
Any trader that watched the intraday quotes coming from Bitfinex knows they went offline around 4pm June 20th (EDT) and then tried to re-open their engine TWICE, while at the same time preventing people from being able to change orders. This resulted in a shit-storm of fear trades and highly imbalanced order book matches.
Bitfinex completely screwed the pooch on this one, but since they get a cut of every order liquidated, I'm sure they could give a shit about everyone getting stopped out or margin called. In fact, the way they came back online suggested a huge stop-run was being encouraged in the first place.
This had nothing to do with Brexit or anything external -- just BFX's complete and utter incompetence.
I completely agree with this. It's a damn shame that what is considered the most important $$$ exchange has messed up so badly. If I look at the silly errors coming from these exchange, I don't find it weird that institutional traders avoid using Bitcoin as investment tool. There is no way they will trust the current exchanges with multi millions while they don't know how to run an exchange properly and in a professional manner.
