The developers of the leading cryptocurrencies are also monitoring the situation and in case of danger there will be new hardforks with a change in the algorithm.
Here's what will happen to Ethereum in 6 months

What attacks are you talking about? 51% attack or private key guessing with a quantum computer?
It is unlikely that quantum computers will be able to make a 51% attack on Ethereum in 6 months

I was referring to quantum computers successfully performing a 51% attack on the ETH blockchain. Private key guessing might not be much of an issue since a quick fix (like Lamport Signatures) could get ETH back on track. It's believed that PoS could put fears of a "quantum attack" to rest in the not-so-distant future. With well-talented developers on the project, you can rest assured that Ethereum will stand the test of time. If all else fails, people would simply migrate to another blockchain that's "Quantum-Resistant". The "Quantum Resistant Ledger" (QRL) is a nice alternative to those who'd want to secure their crypto as much as possible from the rising threat of quantum computers. Time will tell us whenever the field of "Quantum Computing" will pose a direct threat to crypto/Blockchain tech or all the other way around. Just my opinion
