Is Aviator a game of skill or pure luck?

I’ve been debating with my friends for a while now whether Aviator is a game of luck or skill. I’ve played a lot of games where luck is a huge factor, but I feel like there might be some skill involved in Aviator, especially when it comes to timing the cash-out. I know some players who seem to have a better understanding of when to cash out and avoid losing big. Personally, I can’t figure it out and usually end up cashing out too early or too late. What’s your take on this? Do you think there’s a strategy involved, or is it all about luck?
