Of course not
All this marketing about quantum computer destroying bitcoin is ridiculous. I don't get who makes money out of this bullshit.
Maybe they are just spammy article writers who wants clicks?
Yes, I agree with you, I think it's just a hoax because until now there has been no official announcement from Google about quantum computers. and I think if a quantum computer does exist then I'm sure bitcoin developers will improve security systems and strengthen block security. I'm sure bitcoin developers will try hard to strengthen the bitcoin system and network.
We hope that people who use crypto will know that the news is not right, so they don't panic to see if the quantum computer will destroy bitcoin. They should learn from the other news about a quantum computer so they can understand what the right thing from that news is. That doesn't make sense because I am sure bitcoin will adapt to the current situations, and as you said, the developer will always upgrade the system following the growth of the technology.
