We always experience and seen bitcoin in a decline price. When price drops people claim bitcoin to be dead. It does not mean the end for bitcoin. Although price happen to be down it will be skyrocket in time.
I do not think it will end and the bitcoin will disappear, you can see that bitcoin is always what people are aiming for in the future. Bitcoin has great benefits. All transactions are anonymous, absolute security, unlimited transaction volume and size, fast transaction speed. So we can all see that bitcoin prices can be reduced but will last.
