Yesterday was not a good day for the bitcoin ecosystem, that much is certain. Not only did the PBOC impose new AML regulation on Chinese exchanges, but several exchange platforms experienced outages as well. To some people, this looks like one big conspiracy to avoid significant financial losses when the price crashes. It is rather unusual to see so many bitcoin exchange platforms suffer from issues on the same day, though.

No conspiracy theories came to my mind after reading that article. I think the outages happened simply because of a lot of people were coming to sites simultaneously. I agree with advice from the article that cryptocurrency enthusiasts need to move away from centralized platforms and store funds in a wallet they can fully control.
