Velocity is always 'relative', or 'frame dependent'.
A particles has therefore no 'rest mass' and no 'absolute velocity'.
To talk about velocity would require to say, in respect to what that velocity shall be measured.
There are two obvious possibilities in respect to which the particles could be in motion:
the observer
the particle itself
'The universe' is not possible as reference, because the universe does not contain points, which do not move.
Usually the observer is regarded as being at rest and placed in the center of his won coordinate system, because the other possibility is a little pointless as the particle does not move in respect to itself.
