Bitcoin truly is the number one of crypto currencies, taking lead in price and has great effect on the entire crypto market. Having made the popularity of crypto currencies go viral all round the world, it has its own technology that it provides, so does other coins in the market. Every coin has its own uniqueness, not withstanding the its price. ETH has its own technology which is a big foundation that a whole lot of altcoins build on, Tron, and many others. In terms of trading, it takes two commodities to have a successful transaction, bitcoin can't be traded without a trading pair. So, I don't think bitcoin will remove all other altcoins from the market, rather, it will remain to lead in the crypto space.
