Its true Libra coin will bring many changes and competative edge in cryptoworld but to overcome Bitcoin need alot home work and time.Bitcoin is always kind libra coin can take place of queen.
Bitcoin give way to the world to be your own bank and move around the world cashfree.
That's what happened but for new coins even though it's released by a famous platform like Facebook I'm not sure the Libra coin will quickly compete with Bitcoin, because it takes time to achieve something high in this industry but it can be said that it will only take a short time to become big on the cryptocurrency market.
