Facebook's Libra is high fee ETF if private keys aren't distributed, according to BitMEX Research. Although Facebook's consumer reach gives it an advantage over similar ETF's like Blackrock's AGG, a lack of return yield makes Libra a poor alternative. If digital signatures are kept in a meaningful way, Libra does bring valuable cryptocurrency features like pseudonymity, censorship resistance, and tradability with other digital assets. Still, an unclear investment motive and governance by a democratic foundation only make matters worse in the midst of an overcrowded ETF market.
