Morgan Stanley, one of the biggest banks in the US, has jumped into the Bitcoin game with a hefty investment. According to their recent filing with the SEC, they've put over $243 million into Grayscale Bitcoin Trust (GBTC), holding a whopping 4,269,361 shares.

It's not clear exactly when Morgan Stanley made this move, but it's significant. Their involvement comes at a time when the US inflation data was released, possibly influencing market sentiment. This could be a factor in the recent surge in Bitcoin's price, which has seen a nearly 7% increase in the last 24 hours, reaching $65,844.70.

The market seems to be reacting to a mix of factors, including the dovish CPI data suggesting potential interest rate cuts by the Federal Reserve. Lower interest rates are attractive for assets like Bitcoin, known for their long-term yield potential. The trend of accumulating spot Bitcoin ETFs, not just by Morgan Stanley but also by other big players like Wells Fargo and Susquehanna International Group, adds to the positive sentiment.

But it's not just Bitcoin enjoying the spotlight. The market rebound has also lifted many altcoins. Ethereum, for example, has seen a 6.52% increase to $3,025, recovering from earlier losses. Other altcoins like Binance Coin, Solana, XRP, and even Shiba Inu, known for its meme status, have also experienced gains. Shiba Inu's recent migration to ShibaSwap on its Ethereum L2, Shibarium, is seen as a significant move likely to boost its value through increased network transactions.

In summary, Morgan Stanley's significant investment in Bitcoin, along with positive market sentiment and developments like ShibaSwap, are driving the recent rebound in both Bitcoin and altcoin prices.
