[Su Zhu: Not Optimistic About Privacy Coins, BCH is the Most Worth Watching Among 'Antique Coins'] Odaily Planet Daily News - Su Zhu posted on X, saying: 'I am not very optimistic about the prospects of privacy coins. Exchanges will face immense pressure and are likely to reduce their support for them. In fact, Tornado is still the most practical privacy protocol at present. Among these "antique coins," BCH might be the most worth paying attention to. In the coming years, the Bitcoin quantum computing threat narrative may become a common topic, and as the public gradually realizes the difficulty of upgrading BTC, this understanding will further spread.'
