As of my last knowledge update in January 2022, there was no official confirmation regarding the inclusion of cryptocurrency in Grand Theft Auto 6 (GTA 6). Rumors and speculations about features in upcoming video games, including GTA 6, can circulate widely, but they are often unverified until officially confirmed by the game developers or publishers.
If there have been any updates or official announcements about GTA 6 and its inclusion of cryptocurrency since then, I would not be aware of them. To get the most accurate and up-to-date information, I recommend checking the official announcements from Rockstar Games, the developer of the Grand Theft Auto series, or reputable gaming news sources.
The information you provided indicates that a premature leak of the first official trailer for Grand Theft Auto 6 (GTA 6) occurred, with the leaker creating a Twitter account named “Gta6trailerleak” to share the content. The leak included an unusual addition: the words “BUY $BTC” plastered on top of the trailer, promoting the leading cryptocurrency Bitcoin. my last knowledge
Although the Twitter account was swiftly banned, the leaked trailer continued to circulate on the platform. Rockstar Games, the developer of the Grand Theft Auto series, responded to the situation by releasing the official version of the trailer earlier than planned.
It’s important to note that promotional messages or content added by leakers may not represent the actual intentions or features of the official game. Rockstar Games is typically the authoritative source for information about their games, and any confirmed details about cryptocurrency integration or other features in GTA 6 would likely come from official announcements by the game developer.
