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/Those words are misleading, they just want people to ease up on Libra coin so they can launch without oppositions, there's a possibility that this Libra coin will take market shares, look at what happens on Ripple people always compare to these two coins together and soon Facebook will also be compared to Bitcoin.
nothing wrong with comparing coins . almost all the coins on the crypto market are always being compared to bitcoin because some coins have different feature but until now bitcoin is still the leading coin . the same thing will also happen with this facebooks new coin . the tension is only on the start but eventually the tension will loosen up between the two and people will crawl back to bitcoin . and more thing , i disagree with the title . libra coin is really a threat to bitcoin but its not alarming at all .
