Grayscale, the world's largest digital asset management fund, has added Cardano (ADA) to its large-cap crypto fund, making it the third-largest position. Grayscale reported that it had rebalanced its portfolio, with Cardano's ADA now ranking fourth after Bitcoin and Etienne. Earlier this month, the company registered trusts for a number of cryptocurrencies, including Cardano and it appears that it is finally trying to capitalize on the altcoin that had a price and popularity spike in 2021.
