CoinEx News: Bitcoin faced a volatile session on Tuesday, initially sliding toward $66,000 as renewed concerns over Google's latest quantum computing breakthrough sparked fresh debate within the crypto community about the long-term security of BTC private keys. However, sentiment shifted swiftly after Iran's Foreign Ministry spokesperson indicated that Tehran had communicated its position on this war imposed on Iran to mediators, a statement markets interpreted as a potential sign of de-escalation in regional tensions. The perceived geopolitical relief propelled Bitcoin to rebound above $69,000, while Ethereum briefly surpassed the $2,150 mark.
