SharpLink Gaming (SBET) experienced a dramatic stock price fluctuation, soaring 2000% last week before retreating 30% in early Monday trading. The volatility follows the company's announcement of completing a $450 million financing round, with plans to invest in Ethereum as a treasury asset. Ethereum co-founder Joseph Lubin will join SharpLink's board as chairman. The financing was achieved through the issuance of 69 million shares, though only 2 million are currently available for trading due to a registration rights agreement. This limited availability contributed to the stock's rapid rise from under $3 to over $100. The recent decline reflects market adjustments as the initial excitement subsides and supply-demand dynamics shift.
