Zuckerberg is making a big plan. I think Facebook will dominate this market. Bitcoin is the king of this market. What will happen when a new king enters this market. However, if Libra is stable, Bitcoin is still king.
Please don't ever think that Libra coins will similarly have the result same how facebook has its name in the community cause it is totally different.
Libra hasn't attracted investors cause they'll never see good news about their problems. They most likely to feel doubts if this certain coin Libra will take their final launch cause until today, it is still questioned by the regulatory board.
