Solana has brought the quantum security issue to the forefront this time, but the cost is also very direct: increased signature size and a noticeable drop in speed. The high-throughput narrative and security patches are beginning to conflict directly, and the market is likely to focus on the repair costs in the short term rather than continuing to promote performance stories. Sentiment here is somewhat biased, and $SOL and $BTC will also be considered together when assessing the progress of the quantum defense line.
