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.
https://www.ccn.com/crypto/facebook-cryptocurrency-chief-libra-no-threat-to-bitcoin/2019/06/20/I think the former President of Paypal has a reason to get stressed, because in my perception about Libra, that there is a possibility that libra can surpass Paypal in terms of payment system online, but not in Bitcoin of course! Since that we don't have any much proof in it, were everything was just still an speculations let us see what could happen in the next day, weeks or months.
