GameStop shares have outperformed Bitcoin's yearly returns in a single day, with a 154% increase compared to Bitcoin's 129%. This surge occurred after Keith Gill, the man behind the 2021 GameStop short squeeze, returned to social media. This has sparked hopes of a potential altcoin rally, similar to the one that followed the GameStop squeeze in 2021. However, the current investing environment is different, with fewer outstanding shorts on GameStop, which could limit the potential upside. Some meme coins have already seen gains, with Pepe hitting a new all-time high.
