That's a really good question, and one I've wrestled with myself! For a while, I was pretty skeptical, but I decided to take the plunge last month for a game I play regularly. I ended up using LootBar for some top-ups, and the process was actually very smooth. I needed some extra currency for my
kingshot shop purchases, and their prices were significantly better than the in-game store. They delivered the top-up almost instantly after my purchase, which was a pleasant surprise. I made sure to check some reviews beforehand, and everything seemed legitimate. It honestly felt pretty secure and saved me a fair amount of money in the long run.
