There is something I'm thinking though I don't know if it's right or wrong, that Bitcoin is the prime currency here, not necessarily because of its price but because of its blockchain project and being the first in the system so I'm thinking even if other cryptocurrencies price ever get higher than Bitcoin, will Bitcoin still be seen as the prime cryptocurrency? Or is the whole thing around the Bitcoin centered around its current price in the market?
It is a close circle of events. Bitcoin is the most popular cryptocurrency as it was the first one ever. For that reason it absorbs the most value on the market because it's almost always the first puchase whene entering cryptocurrency market. As it is the first purchase it's vale is going up so it's making BTC most popular and so on and so on.
