Hi Jalumi,
Thank you for sharing your thoughts. I see where you're coming from, and I share your concerns as I have previously written about QC's threats to Bitcoin and crypto.

Devs for Bitcoin, Ethereum, Cardano, etc., will find a way to implement a hard fork, most likely before QCs compromise SHA-256 and ECDSA, in the case of Bitcoin.
With all due respect, if hackers manage to break Bitcoin, we'll have even bigger problems on our hands: Bank accounts, medical records and other sensitive data being stolen.
I appreciate you bringing up QC, as it should be on everyone's minds. We need to start making blockchain quantum-resistant sooner rather than later.
Don't forget to take profits along the way, particularly towards cycle peaks.
