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..
Bitcoin will always be the original cryptocurrency, but it's highly unlikely to remain in its dominant position.
Most likely over the coming decades it will be surpassed by others. This is part of the healthy and natural evolution of the protocol.
