and will not be able to survive in long run.
This is one very essential point to highlight(emphasize), is it possible for libra to last a long period of time, if you ask me I'll say it is a no, taking a look at their setup and also their privacy issues, I think libra may not be able to last so long in the market, I even wonder what investors would be thinking going into this sort of investment.
Bitcoin may not be stable, but we all know it's potentials, this potentials it has kept up for the past 11 years or so and still counting, that alone is enough to show that bitcoin is way ahead of libra, there is no definite prove that libra may not last long, but till it does, the bitcoin is in a world of its own compared to it.
