As 2025 approaches its final stretch, CoinGecko data highlights a striking divergence in crypto market performance.
While Bitcoin and Ethereum are closing the year in negative territory, a group of privacy-focused cryptocurrencies has surged into the top ranks of annual gainers.
According to CoinGecko’s latest visuals and accompanying posts, privacy coins are not just outperforming, they are dominating the leaderboard among large-cap digital assets.
Zcash ($ZEC) has emerged as the second-highest crypto gainer of 2025, delivering a 574% return from January 1 through December 18. Only MYX Finance outperformed it, posting a significantly larger gain of 3,358%.
CoinGecko’s chart places Zcash well ahead of most large-cap assets, underscoring a powerful resurgence in privacy-focused narratives late in the year.
Alongside Zcash, Rain Protocol ($RAIN) also posted strong gains of 185%, securing third place in the 2025 rankings.
One of the most notable takeaways from the data is the concentration of privacy coins among top performers. CoinGecko’s rankings show that:
This means three privacy coins ranked inside the top 10 gainers of 2025, a rare occurrence in recent market cycles and a clear signal of renewed investor interest in privacy-oriented assets.
The broader top 10 list also includes Zebec Network, Zora, OKB, Alchemist AI, and Maple Finance, but privacy coins stand out for their consistency across the leaderboard.
CoinGecko’s comparison chart highlights a sharp contrast between altcoin performance and the two largest cryptocurrencies.
Despite reaching new all-time highs earlier in the year:
In CoinGecko’s visual ranking, both BTC and ETH appear near the bottom of the performance chart, reinforcing how dramatically they underperformed relative to privacy coins and select altcoins.
Taken together, the three CoinGecko screenshots paint a consistent picture: 2025 rewarded niche narratives over incumbents. Privacy-focused projects not only outperformed Bitcoin and Ethereum, but also secured multiple top positions among the year’s strongest gainers.
As BTC and ETH finish the year with losses, CoinGecko’s data shows that investor attention rotated decisively toward privacy, utility-driven altcoins — reshaping the performance hierarchy of the crypto market in late 2025.
