What is happening to the volume of TrueUSD?

[wxa7115]

A few weeks ago its volume was very high reaching 300 millions each day and today that sum is around 80 millions, while its market cap is unaffected I find this drop to be too significant.

So I am wondering what is happening? Is this just a natural fluctuation because the price of bitcoin is not really moving that much and the pandemic is forcing a lot of people to sit on the sidelines or is there something else I am failing to realize?
