You sound so convinced that a good number of people already know about Bitcoin, and therefore, the GTA games will not make much of an impact. That is quite a way to underrate their efforts. Firstly, you may think that Bitcoin is already getting fair attention, but do not be surprised by the number of people out there who still do not know about Bitcoin or those who are not fascinated by Bitcoin and what it stands for.
We should not underestimate what a little exposure can do. Bitcoin has indeed gone global, and it will even do GTA VI a lot of good, but there are still people that Bitcoin will reach through GTA.
The majority of the people who play GTA know about Bitcoin. There are very few young people who are active online, or active enough to be fans of GTA, that haven't heard of Bitcoin. I'm not saying they know or understand what it is, but they have heard about it before. It's not all of them, but the majority of them. At least 60% of them have heard about Bitcoin. So seeing it in the game won't suddenly make them start buying Bitcoin.
I did not say it has no relevance. What I mean is, on its own, it doesn't really do much, but when there is a collection of different little gestures like this, then it will have an impact. That is why I said the more ads, the more videos, video games, movies, etc., that Bitcoin gets mentioned in, that's when it will have a huge impact.
