Elon Musk has intensified his critical stance towards cryptocurrencies in 2025. Recently, he backed a warning about a possible collapse of the US dollar, suggesting that Bitcoin could "take control" in response to uncontrolled government spending. Furthermore, he has launched XChat, a new messaging feature on his X platform, which uses "Bitcoin-style" encryption. However, security experts have questioned this claim, pointing out that Bitcoin does not employ encryption in that way. Regarding his investments, Tesla continues to hold a significant amount of Bitcoin, while Musk warns about market volatility and advises against investing savings in cryptocurrencies.
