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.
