The high market value old coin ZEC has surged 10 times in a month, leading to a privacy race. I would like to write an in-depth investment research article for everyone. -Upward logic In this round of privacy coin rise, ZEC played a leading role, with both emotional excitement and financial logic supporting it. 1. Renowned Silicon Valley investor @ naval (author of "The Naval Code") wrote in October 2025: "Bitcoin is the insurance against fiat currency, while Zcash is the insurance against Bitcoin. ”This statement quickly ignited social media, sparking discussions among mainstream KOLs and communities, making ZEC the new focus of privacy narratives. 2. ZEC is approaching a halving of block rewards, and the market's expectation of tight supply has further fueled the rush to raise funds. Against the backdrop of stricter regulation and widespread use of on chain monitoring tools such as Arkham and TRM, privacy assets are being revalued, and the proportion of Zcash "shielded pool" transactions continues to rise, strengthening its practicality and long-term value. The entry of institutional funds has injected a signal flare into the market - including Arthur Hayes' Maelstrom fund, which has listed ZEC as the second largest holding (Coinfomania), indicating that this narrative is being accepted by the capital level. With the phased weakness of mainstream assets and the opening of market rotation, privacy coins have become the "undervalued+new narrative" sector in the eyes of funds, and ZEC, with its narrative, fundamentals, and resonance with funds, has occupied the perfect cutting edge position and become the leading rising target of this round of privacy sector revaluation. -What is Privacy Coin? First appeared in 2014, representative projects include @ Monero and @ Zcash The core goal is to protect individual transaction privacy and prevent asset flow from being publicly tracked in a decentralized system. Unlike traditional public chains such as BTC and ETH, privacy coins hide the sender, receiver, and amount of transactions through technologies such as ring signatures, zero knowledge proofs, or mixing. The strength of Zec has also driven other tokens within the sector, as shown in the table below. It is not difficult to see that the difference in privacy coins is essentially a divergence in technical routes: -Ring Signature Mixing real signers into multiple sets of signatures makes it difficult for the outside world to identify the source of the transaction. Monero is a typical representative. -Zero knowledge proofs (ZK SNARKs/Halo 2) Allow users to prove to the verifier that the transaction is legal without disclosing transaction information. Zcash and Firo are representative projects. -CoinJoin/PrivatSend Mixing transactions from multiple users and blurring the flow of funds. Dash uses this type of scheme. -MimbleWimble Protocol Aggregate transactions and delete redundant information to achieve a "lightweight privacy blockchain", adopted by Beam and Grin. Privacy is evolving into a core component of 'identity sovereignty'. As the token itself is rising for speculation, I think the liquidity is not good now and I will not participate temporarily.
