  In Ref. [1], Minkov et al reported the time dependence of magnetic moment of
hydride materials under high pressure in a diamond anvil cell. Here we point
out that the straight lines interpolated with the measurement results give the
misleading impression that thermal flux creep in superconductors decays
linearly with time. To dispel this misconception, we correctly interpolated
logarithmic decay curves. Then, it has become apparent that there is no reason
to assume that the measured magnetic moment originates from flux trapping,
i.e., there is no reason to believe that persistent currents are circulating in
hydride materials under high pressure and that they are superconductors.
