Free V-Bucks in Fortnite?

Have a PS4 (if that's important). If you want to buy skins for V-Bucks, do you know how to get them for free? Because I have never bought any with real money and suddenly had 100 V-Bucks

Sometimes you get some in the bp

Do not give in vain

You just have to play a lot. You sometimes get 100 free points with the Free Pass. The Free Pass is the gray line above the Battle Pass.
