Till exchanges reverse trades, as has happened already (hint, Gemini and GDAX).
I don't use corrupted exchanges (ie. licencied exchanges like NY licence).
And we already others actors that they freeze bitcoins, too :

Ultimately all of them have the capacity to rape their customers and I suspect many do. Either by front running, messing with orders, freezing trades to customers while they can still trade and on and on.
A genuinely trustworthy exchange has yet to come to light. All of them are up to something either through malevolence or incompetence.
