Is CSGO Dieing?

Seems like OP has been banned but I'll still share my two cents for those browsing the thread.

According to http://steamcharts.com/app/730#1y the playerbase has stayed relatively steady in a decline, though it's a decline that's to be expected. The impressive part is that it's only within 200k players less than it had a year ago. With PUBG coming out it's still done pretty well keeping top 10 games on Twitch (viewer wise). The game is also within the top 10 on steams most played (monthly statistics) page.

At this rate the game doesn't seem like it will die any time soon really. Player base will decline but the death of a game, in my opinion, is when you queue for a game and you get the same people over and over, or you can't queue due to lack of players. When this is for sure not an issue in game.
