Bitcoin is proving to be extremely strong, practically "immune to death". If you look at Bitcoin Obituaries, people among the most influential and powerful in the world (let JPMorgan CEO be one example) have been unsuccessfully trying to bring it down. Even Hearn tried to destroy it and, despite all the incredibly negative promotion worldwide, Bitcoin's price went down a little only to (slowly) get back. If not even one of its creators was able to kill it, who will?
pffft.......Give it time.
Bitcoin at the moment, is essentially a cash cow for whales. If Bitcoin is to have another 'moment in the sun', then it will coincide with a Chinese Economic collapse and Capital Flight out of the CNY. Beyond that, Bitcoin don't have nothing going for it that competing cryptos don't do much better and has plenty things wrong with it that other cryto's don't have.
Blockchain is here to stay (unfortunately), but Bitcoin isn't.
