I think not, altcoin can not be against its king, there are not any opportunities or a way to altcoin can against Bitcoin because bitcoin is the common currency of digital coins and all altcoin must be converted to bitcoin on the exchange. In previous years, many people telling me that eth or litecoin would replace bitcoin, bitcoin would be defeated but until now I still do not see any sign of bitcoin being defeated. I only saw the value of Bitcoins is still constantly increasing and altcoin collapsed under its feet, it is proving the status of a king and despise those who want to against it
