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

How is Gulden Market Cap calculated?

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

Gulden Market Capitalization in USD = Number of NLG in supply X Price of one Gulden in USD

Since the price of Gulden 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 Gulden or predict the price of Gulden.
