So this essentially implies Coinbase needs to manipulate the market in order to ensure their profitability?

How does it implies any kind of manipulation? Check out these videos for what a market maker actually is: https://www.youtube.com/watch?v=QqK6H1JPjv0 https://www.youtube.com/watch?v=QqK6H1JPjv0 https://www.youtube.com/watch?v=Guqs3eOgm6o https://www.youtube.com/watch?v=Guqs3eOgm6o

  But what happens if the market moves rapidly in one direction? They end up selling low and buying high. So, they need to reset the market making algorithm. Or shutdown the exchange for a "fix", long enough that the volatility comes back in their range. Disabling a feature during live trading in order to ensure your company doesn't lose out on profitability, which in effect impacts market trend and activity implies manipulation. As a neutral platform whose sole purpose is to provide a place for people to buy and sell, you're essentially influencing the market by disabling/enabling buy/sells, especially at heightened times of flux.

    I corrected my mistake of calling the whole thing an "exchange". Corrected it now. As many have pointed it out on this thread, GDAX - the exchange works just fine. So people who are worried about selling/buying can find a willing participant on the exchange. But, Coinbase's main site is just another willing participant just like you and me in a given trade. It can refuse to take the other side of the trade if it affects their profits. If you still insist it is "manipulation" then I digress.

  Declining to allow trades during high volatility times is definitionally market manipulation - you're capping the volatility of the market, unpredictably. Volatility is traditionally where many styles of traders actually make money.
