  Let $K$ be a number field, and $g \geq 2$ a positive integer. We define
$c_K(g)$ as the smallest integer $n$ such that there exist infinitely many
$\overline{K}$-isomorphism classes of genus $g$ hyperelliptic curves $C/K$ with
all Weierstrass points in $K$ having potentially good reduction outside $n$
primes in $K$. We show that $c_K(g) > \pi_{K, \textrm{odd}}(2g) + 1$, where
$\pi_{K, \textrm{odd}}(n)$ denotes the number of odd primes in $K$ with norm no
greater than $n$, as well as present a summary of various conditional and
unconditional results on upper bounds for $c_K(g)$.
