This is from the file you linked yourself above:
static const int64_t MAX_MONEY = std::numeric_limits::max();
That does mean there is no max supply for VIDZ, so number of coins will be growing indefinitely, until blockchain exists and is moving.
But with inflation of 1440 coins per day that is not important. The grow rate is extremely slow.
In 10 years there will be about 130M VIDZ, in 100 years - 175M.
Are you interested in bigger timeframes, for example thousand or a million years?
