Crypto analyst Zack Voell has noticed a pattern where the reintroduction of McDonald’s McRib sandwich has aligned with bullish trends in the cryptocurrency market. Since 2016, out of the last seven instances, Bitcoin’s price has surged four times following the sandwich’s return. Notably, the most significant returns were witnessed in 2017 and 2021, coinciding with bull rallies in those respective years. Conversely, two instances in 2018 and 2022 saw the sandwich’s return accompanied by significant downturns in Bitcoin’s value.
