You can check out above graph to see how the market cap of Datum has changed over time. The market cap value depends on the value of Datum on that particular day and number of Datum in supply at that day.

How is Datum Market Cap calculated?

The Datum Market cap is calculated using a simple formula. You can find it below:

Datum Market Capitalization in USD = Number of DAT in supply X Price of one Datum in USD

Since the price of Datum is highly volatile you can see the market cap going up and down a lot. Sometimes price and market cap are not linear to each other due to increase in the supply of coins in the market and stable or decrease in the price of the coin. So you can say that it's not simple to predict the market cap of Datum or predict the price of Datum.
