I am writing in full support of this proposed rule change. Ether (the tradable asset in Ethereum) is trading in liquid markets and has great price transparency. The previous generation of futures-based products for digital assets was created solely as a workaround because previous rules were opaque. Now that decisions are coming which provide clarify the rules, this next generation of spot-based products will better serve investors. And I appreciate you taking the time to read this comment and to everyone working on this proposed change. Sincerely, William Entriken Lead author of the document ERC-721 (the document that started NFTs discussed in this proposed rule change), and a contributor to commercial products and protocols working on Ethereum and related technologies.
