No,

Bitcoins currently has the largest percentage of the total crypto market cap, and as long as the total market cap increases I believe bitcoin value too will keep increasing. Also, bitcoin still remain the entry point for so many newbie crypto investors.

I also agree that an innovative altcoin could take Bitcoin down one day, but it doesn't look like that's gonna happen anytime soon, so I believe bitcoin will be here and still be bitcoin for a long time.
