Privacy coins like Monero and Zcash may face increasing regulatory pressure, which could lead to their marginalization. Governments are tightening regulations around privacy, and cryptocurrencies that emphasize anonymity could face restrictions or bans. As a result, these coins might become less accessible to mainstream users and investors, while potentially being pushed to the fringes of the crypto space. However, the demand for privacy solutions may keep these coins relevant in niche markets despite regulatory challenges.
