Why vote when the American election is forever tainted?

This is not my first time voting, I remember when it used to be fun to vote, now I feel like voting has no meaning anymore as I’ve learned that no matter who wins, the only side will say they cheated. So why bother to vote? My vote, your vote doesn’t matter, at the end of the day it’s whoever has the final say will declare the victor. These elections recently has been so exhausting that I just tell everyone don’t even bother to vote. It won’t matter who wins, every election going forward in history will always be deemed fraud. What are we supposed to do now?
