It’s pretty much the same in a parliamentary election system with an electoral threshold.
If the party you vote for can’t clear that threshold, you might as well not vote at all.
I guess your vote still has a slight impact, as it makes it harder for other parties that hover around the electoral threshold to get in. But I doubt that’s the impact you are going for.
Oh right… I forgot about that, must have had an actual democratic system in mind :/
