Options on XRP exchange-traded funds listed in Canada have been registered for sale to U.S. investors, expanding access to regulated XRP-linked derivatives. The Canadian Derivatives Clearing Corporation registered options based on the Evolve XRP ETF and Purpose XRP ETF under the Form S-20 framework. The filing does not mean the options are directly listed on a U.S. exchange. The framework already covers options tied to bitcoin, ether and solana ETFs.

A debate over Bitcoin\'s 21 million supply cap has resurfaced after early developer Peter Todd raised questions about long-term security under declining block subsidies. The issue is whether transaction fees alone can sustain proof-of-work security as halvings reduce subsidies. Todd has floated “tail emission,” continued small issuance after new issuance ends, though he has not proposed a concrete change plan. Critics call the idea risky, warning it could undermine trust and threaten Bitcoin’s viability.
