VanEck's digital-asset research chief, Matthew Sigel, has cautioned public companies against the risk of shareholder value dilution when issuing shares to purchase Bitcoin. As Bitcoin trades near $106,600, Sigel warns that firms like MicroStrategy and Marathon Digital, which hold substantial Bitcoin reserves, may face volatility if their stock prices approach the Bitcoin net asset value (NAV). He cites Semler Scientific's share price drop as a warning, urging companies to monitor share-to-NAV ratios and consider buybacks to safeguard shareholder interests. This advisory comes as institutional interest in crypto surges, with $1.9 billion in inflows reported in early June.
