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

How is Pluton Market Cap calculated?

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

Pluton Market Capitalization in USD = Number of PLU in supply X Price of one Pluton in USD

Since the price of Pluton 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 Pluton or predict the price of Pluton.
