Bitcoin's price is flying and rising with rocket speed.. i think bitcoin will survive always as the leader while it may have competitor but i think bitcoin is the most expensive and most well-known coin in crypto currencies. So it will stay as it is..
With the bitcoin becoming more expensive and harder to mine, people who are new to it find it very difficult to get their hands on it, especially if they dont have the money for it, so their option is to switch to other crypto currencies and try to mine those and then hopefully exchange them into bitcoin, but that does not mean that they will replace bitcoin.
