Justin Sun, the founder of Tron, is one of the wealthiest figures in crypto, and much of his bitcoin (BTC) is held in one location: the United States-based Valkyrie Investments. According to a private financial document reviewed by CoinDesk, the altcoin kingpin had more than $580 million in BTC stashed with the crypto asset manager at one point in August. According to the document, this amounted to more than 90% of the money at Valkyrie’s largest division, Valkyrie Digital Assets LLC. In other words, Valkyrie Investments, a Wall Street-focused money manager, relied heavily on Justin Sun, a controversial Chinese crypto billionaire.
