As long as there is crypto, I am very sure that Bitcoin will always be there and need each other. it is very difficult that bitcoin will disappear from circulation or disappear
I feel pity at times for people like OP who think bitcoin will die, bitcoin will reach to 1000, or 100$ etc. Because of such stuff they will never invest in this booming market and thus will never get a good return which they could make form crypto currency. Instead they will be spectators only and just keep on seeing and at the end of the day will regret as they will see btc will reach 10, 15 or 20k in coming years
