Is it possible to happen? Altcoins crushing bitcoin in terms of price, trading, etc.? I am just curious about all of your thoughts, so don't hesitate to reply and get yourself justified 
Even if other crypto is far better than bitcoin in terms of technical functions, bitcoin is still the most popular and has more people using it. It's all about network size. Because your question is related to price speculation, I don't think there is an altcoin now that can replace Bitcoin and take the throne. Bitcoin is king and there are many who claim they are better but never prove its value.
