David Marcus, the head of Facebook's cryptocurrency Libra twitted,
Many want to pit Libra vs. Bitcoin. In my mind these two are not in the same category. BTC is a decorrelated (investment) asset. Libra is designed to be a stable medium-of-exchange. I have been, and remain a fan of BTC, but for very different purposes.
The former president of Paypal stressed that Libra is a better digital cash and payment system, while bitcoin is a long-term investment vehicle.
