And as BitMaxz said: "if you don't have knowledge in Linux you can't easily use it the same as bitcoin."
People in crypto misunderstand tail emission. Grin outputs linear reward: 1 coin per second. This is a constant emission. As supply gets bigger, this emission eventually goes to 0. Over long-term, it'll behave like zero supply. I'm not sure how their developers decide on this emission. It seems like an effort to differentiate but they didn't really think through.
