There are major differences between Bitcoin and Facebooks introduction Libra. Bitcoin is a highly volatile asset and fluctuations in its price are frequent. Libra on the other hand, is more of a stablecoin that is backed by actual currencies (USD, EUR) and commodities (Gold, silver).
Libra aims at becoming a more main-stream crypto currency and decreasing the factor of risk from crypto trading. It seems that in the future, Bitcoin will become a more investment asset like real-estate or gold.
Even at the moment, people are beginning to hold bitcoin as store of value despite its volatility because they all believe in the future of bitcoin, Facebook on the other side may also not be restricted to stable coin alone, because they will want to create a coin that also have volatility based on what one of them said, he claim that Libra coin will also serve as digital assets but will in no way compete with bitcoin, so we can still expect some sort of volatility in the coin too so that people can benefit from holding it.
One main reason why it would never beat bitcoin is because as we know that bitcoin is still the only coin that seems to be operating on a decentralized platform which is why majority of its users is seriously holding on to it as the most reliable coin.
