Man you have no clue what you are talking about, I been talking about exchanges for months, we lost HitBTC, Bithumb, Upbit, Poloniex, Shapeshift long before this incident.
If that is the case, then why are HitBTC, Bithumb, Upbit still listed on Coinmarketcap.com as having STEEM trading pairs? Coingecko lists those pairs, too.
In fact, you can check for yourself that Bithumb has a STEEM trading pair:

Here's HitBTC:

Upbit:

Poloniex:

Shapeshift (via Coincap):

Turns out your info was completely false.
I was specifically told by one exchange that the reason why they had to take that measure was the result constant selling by a select few who then pull the Bitcoin from the exchange which result in lost of business for the exchanges and the customers. What blown out here, is just the ice-berg, one case, one exchange literally sent back 600K of Steem, that when things got really tight during Bitcoin bear market. Its all business at the end of the day
So you're saying that some people were exchanging so much STEEM for BTC on that exchange that they had trouble keeping up buying enough BTC? That must have been some tiny exchange with very little liquidity to begin with of some pesky STEEM was capable of draining them of BTC.
