Host: With so many ETFs out there, what makes yours unique and what should advisors look
for to differentiate your products from the rest?

Krista Lynch: We are really differentiated by our history of being crypto focused. A lot of people don't realize Grayscale has been around for over 10 years, initially launching GBTC in 2013. We are the pioneer of really bringing this exposure to market and continuing to innovate in a way that's both compliant with regulatory needs, but also can help investors get access to really niche and new exposures in the digital asset space. And recently we've continued to innovate. We actually spun off 10% of the assets in that flagship fund into what is now the lowest cost spot bitcoin ETP in the US by expense ratio. So we continue to hear what our investor demands are. We wanna keep bringing innovative products to market in a compliant form. And that's really been our heritage and will continue to be our marching plans forward.
