Why yes we can. The visionary pioneer of stablecoins (and occasional mathematician) Cauchy came up with a theorem to determine if the path you take with your investments in fact adds up to zero.
We do not just hope that our coin has a stable value. We constantly check contours of complex functions to ensure your investment remains at zero at all times.
