I think it is hard to imagine the crypto world without bitcoin and despite what people said that bitcoin may not survive, I think it is here to stay. But IF bitcoin continues to fall and it does not survive, which of the alternative cryptocurrencies do you think can take its place? Ripple? Ethereum? EOS? Will it be bigger than bitcoin?
Everything has a beginning and an end, but Bitcoin is very far from the end. There is no reason to worry about it at all and the rest of the coins may even surpass bitcoin but it will still be there.
