It's not easy to be able to compete with Bitcoin, let alone replace the position of Bitcoin as the king of cryptocurrency, Libra coins have not been launched and will be released in 2020 and in my opinion is too excessive if it is said to compete with bitcoin because libra coins have not been launched.
Bitcoin is the most popular coin among other coins, and even though Libra coins will be launched later it seems too early to compete with bitcoin and must go through a long process.
