It is a potential threat. We don't have any reason to believe security won't simply be quantum to match quantum processing. But a big question would be why would someone want to use it? It wouldn't go unnoticed and it would devalue the whole thing were you got do any block manipulation. The only chance you have is at finding dead wallets that really have no owners and guessing their private key.
Ironically though we are moving away from quantum and all money is being put into bandwidth; which is how AI works.
You're correct, it was a short window. That is the life of many meme coins. There were guys that were not insiders that made tens of millions off of it in that time span. Buy shit loads, ride it up, sell before inauguration takes place, pile it all into shorting it. Buy the rumor, sells the news.
That seems to get missed, does it not? And funny enough basic use of quantum would get blocked by something as simple as "too many attempts were made" on countless platforms. The speed to which you make guesses is only as useful as how many you can verify. The ways around that stuff could be used at a quantum level but the amount of stabilization you want left in the world is a consideration.
