Analysis suggests a double-bottom \'W\' pattern is forming on bitcoin charts, indicating a possible end to the downtrend. John Bollinger, creator of Bollinger Bands, said the pattern could be a meaningful signal unlike prior rebound attempts. He pointed to a fractal structure and urged looking at weekly charts for a higher time-frame \'W\'. He said a break above about $65,000 could signal the downtrend ending, though ETF outflows and rate-hike worries persist.

Researchers at the Massachusetts Institute of Technology have developed a dedicated operating system, Fractal, to precisely analyze semiconductor internal behavior and security weaknesses. Using it, they examined security features in Apple’s M1 chip and confirmed CSV2 blocks speculative execution across privilege levels. They also found a phenomenon in which code is fetched into the instruction cache before CSV2 takes effect, potentially observable via a side channel, and identified “Phantom Speculation” in Apple silicon used in iPhones and iPads.
