What if google attracts millions of new investors? what if crypto fails to attract investors? Google may make the path harder
I think you just exaggerate things, if there is risk with quantum computing, then bitcoin or blockchain technology will adapt, simply as that. Of course bitcoin is a speculative asset that's why the price is affected by any news, be it positive or negative. Good if Google attracts millions of investors but it doesn't mean that it will make it harder for bitcoin or the rest of crypto in general to grow. Investors like to diversify, so you could see them going to precious metals or stocks or even crypto, nothing to worry about at this point.
