XRP, XLM, and LINK have outperformed other top 50 cryptocurrencies by market cap in the past week, causing Bitcoin's market dominance to fall below 50%. This has led to speculation about the possibility of an altcoin season. XRP has seen a 70% increase this month due to a favourable ruling in the Ripple vs. SEC case, while XLM has rallied by over 50% and LINK has added more than 20% to its value following the release of its CCIP protocol. Shiba Memu, a meme coin project that combines AI and blockchain technology, has raised over $1 million in its presale and could potentially see its SHMU token rally higher in the future. It is important to conduct your own research and understand the risks before making any investment decisions.
