Join a competitive team to become a better play and to win prizes

I'm a 23 year old gamer that enjoys to play on multiple consoles. I started off playing on Xbox One but now also play on PC, Playstation 4 and Switch.
I have been playing Valorant since the middle of the Beta, trying to get my head around some of the game play as I have been playing CS:GO casually since 2015 and watching it religiously also since 2015.
I am really enjoying the game and feel that I have a very good idea about how the rounds go/how everything will play out.
I'm currently not the best player in the world but I am looking to get better and join a competitive team.
