Waves suffered a "flash crash" in the afternoon of the afternoon. At around 16:52, the WAVES/BTC price plummeted to 0.0000001, but then reverted to the previous price. This flashback appears to have occurred only on the Currency Exchange, with a sell order of approximately $530,000. The cause of the accident is still unclear, but one might guess that this may be due to a large sell-off. An encrypted commentator named Emptybeerbottle on Twitter pointed out that this is why setting a very low buy order is a very good idea. At present, the currency has not responded to this incident.
