Accounts go down in general these days. It's nothing exclusively in connection to CyDy. Inflation is rising and money is being shifted from securities into bonds.
In addition to that one thing seems quite telling. After having a very low trading volume for dozens of days, today there was a volume of more than 4 million shares. Why the sudden selloff? Either weak hands or massive shorting. It's obvious that with such a low volume it's easy to influence the SP.
