Because we are not currently a publicly traded or IPO'd company, your XY Equity is still privately held.
This means that you cannot track the current value of your shares with an exchange, like you would for a company that has already experienced an IPO.
In the meantime, you can still hold onto your shares, or even sell them to a new individual to make a profit.
