How to buy VP in Valorant?

Hello there! I'm curious about purchasing VP, or Valorant Points, in the popular game Valorant. Could you walk me through the process step-by-step? I'm new to the world of cryptocurrency and online gaming transactions, so I'd appreciate it if you could explain it in a way that's easy to understand. Specifically, I'd like to know how to use my credit or debit card, as well as any alternative methods like using cryptocurrencies or gift cards. Additionally, are there any safety precautions I should be aware of when making such transactions? Thanks in advance for your help!
