Coincidence? Let the charts speak for themselves: http://thecryptosyndicate.com/opinion-bittrex-anomaly/
Thanks for posting this, was about to make a thread with that exact article. The points in that article are poignant alarms. What's mildly interesting is that there were hundreds - if not thousands of people claiming that their Bittrex accounts were locked about a few days after that manipulative incident happened. Also, the majority of people with locked accounts were located in the middle east - In my opinion, they are not only complying with the SEC (as they proudly and openly state on their website), but they are also complying with intelligence agencies.
I'm glad to say I have taken all of my investments out of Bittrex and into a few DEX (Crypto-Bridge, IDEX, Etherdelta, Openledger). As I see it, only negative outcomes can come from centralized exchanges. Decentralization is the primary protocol of cryptocurrencies and exchanges should replicate that - we've seen what centralization has done in the past and we KNOW it is set for failure.
