Will BITCOIN be replaced?

Hey People!

Bitcoin has a strong dominant place in the cryptocurrency's.
Almost every exchange and brokers used btc as trading coin. But there are so many
other currency's with much more benefits like transactions speed, less high fees.

In the main stream media they almost talk only about the Bitcoin, if Bitcoin is THE cryptocurrency
but we all know its A cryptocurrencys. I think this gives Bitcoin a to big boost.
What is your opinion?
Shall Bitcoin be replaced by an other coin?
So yes, which one and why?
Which timeframe?
Or will bitcoin always dominate the world of cryptocurrency's?
