GDLC, an exchange traded product, is not registered under the Investment Company Act of 1940, as amended (“40 Act”), and therefore is not subject to the same regulations and protections as 40 Act registered ETFs and mutual funds. GDLC is subject to significant risk and heightened volatility. Cryptocurrency assets are not suitable for an investor who cannot afford to the loss of the entire investment. An investment in GDLC is not a direct investment in Cryptocurrencies. Topics we'll cover: What is the Crypto 5? How do we define crypto large caps? What are the benefits of investing in a multi-token fund such as GDLC? What is the methodology underlying GDLC? How does GDLC compare with other options in market? How does GDLC fit into a portfolio?
