Crypto is NOT the prudent choice for a digitial reserve asset, for several reasons.

#Bitcoin is established with the highest market capitalization, liquidity, and global recognition, which are crucial for a reserve asset. 

Its decentralized nature without a central authority or pre-mined supply (XRP, ETH and almost all crypto tokens are pre-mined) aligns better with the principles of what a reserve asset should represent - a trustless, secure, and transparent system. Bitcoin's PoW (Proof of Work) consensus mechanism provides robust security through the world's largest computer network, something XRP's consensus protocol lacks in terms of security depth.(1)

Bitcoin's fixed supply cap at 21 million offers a deflationary aspect acting as a hedge against inflation, which is a key consideration for any reserve asset. In contrast, XRP has a very large pre-mined supply, which raises concerns about centralization and manipulation, especially since you, Ripple Labs, holds a significant portion of this supply. This could potentially undermine the trust that's necessary for a federal reserve asset.(1)

Also, Bitcoin has demonstrated resilience and stability over time, surviving numerous market cycles, regulatory scrutiny, and technological challenges. Its history and track record provide a level of confidence that XRP and most crypto tokens included, with their relatively shorter history and more centralized control, cannot match. Bitcoin's widespread adoption and acceptance as a 'store of value' further supports its case over XRP, which is more focused on facilitating cross-border payments and promoting CBDCs (2) - a use case that, while important, doesn't necessarily qualify it for a reserve asset role.(3)

So, the attributes that make an asset suitable for a federal reserve - decentralization, security, fixed supply, and widespread trust - are more robustly embodied by Bitcoin making it the safest, the most trustworthy and overall superior choice.
