Grayscale Investments LLC, a prominent cryptocurrency asset manager, has seen its portfolio surge by over 85% in November, driven by significant gains in altcoins. Stellar (XLM) led the charge with a 469% increase, followed by Ripple's XRP with a 262% rise, attributed to speculation around Ripple's potential ETF, and Decentraland's MANA with a 105% gain due to growing interest in the metaverse. XRP has notably climbed to become the third-largest cryptocurrency by market cap, surpassing Solana (SOL) and Tether (USDT), with its value reaching a six-year high of $2.48. This altcoin rally has contributed to a broader market trend where the total market capitalization of cryptocurrencies has reached $3.65 trillion, surpassing Apple Inc.'s market cap.
