playstation and xbox gift cards

i found a 50$ ps giftcard and a 50$ xbox giftcard from like 3 years ago and can i use it for valorant? like is there a way to use it for valorant

Only if you sell them to people who use console and take the money you made and put that into val.
The cards themselves, no you cant use them for Val.

Unless there is a console release in future of course.
