If quantum computing poses any kind of threat to the Bitcoin network, then perhaps the developers will also take anti-quantum measures. However, how true or false this is cannot be said at the moment.
Quantum computers are years above us but I don't know why people spread many bad runours about it. We need understand that people spreading FUD about Bitcoin Quantum threats are anti Bitcoin and they don't really care much about Bitcoin, they don't want to see Bitcoin progress. Anytime you see Bitcoin and Quantum news, it's usually spread by people that doesn't hold Bitcoin, we need to understand this earlier and forget about this FUD people are spreading about quantum threats.
