Max Keiser, one of the most prominent supporters of Bitcoin, has drawn attention again with a post that spread on the X social media platform. Keiser claimed that companies like MicroStrategy are using the accumulation of Bitcoin as a tool to exploit weaknesses in the American financial system. Keiser described this trend as a "speculative attack" on the US dollar. He argued that this is only possible because central banks artificially keep interest rates low through mechanisms like quantitative easing and yield curve control.
