Made a guide listing some of the pubg trading sites that's out there, it's not the best guide out there but it's start and hopefully it can help you abit with your trading, also I hope I'll be able to make more pubg trading guides in the future (when the economy has evolved and I learned more about pubg trading)
You can find the guide here:
New guide on the blog, a simple guide about buying cheap keys and how you can make some profit with em. Mostly aimed towards new traders but I'm sure more experience hustlers can find something useful from this.
