as of my own opinion, no. it will be really hard to replace bitcoin. why? because, everyone knows bitcoin has a high value and 1st placed at the market in crypto world. even getting an account is really hard because of a certain process. so if anyone would thought about replacing bitcoin, it will be like impossible to replace them. also many companies uses bitcoin and knows that bitcoin exists, so if other crypto pop up, bitcoin is what still the would recommend all over again. although we know other crypto, why did we still chose bitcoin? why are we posting and answering tight now?  its because we trust bitcoin and its better than any crypto.
