how long will bitcoin remain number one?

This question I asked also a couple of times on Steemit and musing-io and not too many believe it will always remain the no.1 crypto. I also believe that at some point in the near future Bitcoin will be sent to the second place of the crypto charts. Who knows, maybe ripple will be the one to do that with all the hype around it and the launch of xRapid right around the corner. Till then it's still the king and nothing seems to threaten it.
