Throughout 2025 and in the first few months of 2026, the crypto market exhibited severe price volatility and rapid shifts in market narratives. Although the entire market entered a mature phase with increased institutional participation, certain specific sectors, particularly DeFi, AI, and privacy coins, continued to show high volatility.

This report examines the performance of the top 100 cryptocurrencies by market capitalization over two different periods:

• 2025: January 1, 2025, to December 31, 2025
• 2026: January 1, 2026, to May 25, 2026

Price changes are calculated based on the percentage change between the starting and ending prices of each token during the respective periods.

Percentage Change (%) = (( Ending Price - Starting Price ) ÷ Starting Price ) × 100

Subsequently, tokens are ranked based on the magnitude of their percentage price changes in each period. To ensure the analysis reflects market-driven price discovery mechanisms, stablecoins, wrapped assets, and synthetic pegged assets are excluded. All price data is sourced from CoinGecko, as of May 25, 2026, and denominated in USD.

Zcash Leads 2025 Volatility with an 812.5% Increase

Zcash (ZEC) became the most volatile asset among the top 100 cryptocurrencies in 2025, with its price soaring from $56.1 on January 1, 2025, to $511.92 on December 31, 2025, an increase of up to 812.5%. Its outstanding performance reflects a renewed interest from investors in privacy-preserving digital assets amidst an intensifying global discussion around financial regulation and trading privacy. As one of the oldest privacy protocols in the crypto space, Zcash benefited from the market's renewed appreciation of its underlying utility.

The native asset of the WhiteBIT exchange, WhiteBIT Coin (WBT), ranked second, climbing from $24.56 on January 1, 2025, to $56.41 on December 31, 2025, an increase of 129.6%. Its price rise reflected a broad increase in engagement within the exchange ecosystem, accelerated by centralized trading activity throughout the year.

Monero (XMR) followed closely behind, with a price increase of 124.2% during the same period, rising from $193.24 to $433.18. As the largest privacy-centric cryptocurrency on the market, Monero's performance solidified the strong position of the privacy narrative in 2025. OKB ranked fourth with an increase of 122.9%, from $49.07 to $109.35, primarily benefiting from OKX's global expansion and token burn mechanism.

The Artificial Intelligence Superintelligence Alliance (FET) ranked fifth, but unlike other listed tokens, its price volatility was mainly driven by a decline. The token's price dropped by 84.2% from $1.27 on January 1, 2025, to $0.2 on December 31, 2025, reflecting a general pullback in AI-related crypto assets after early speculative excesses.

This stark contrast highlights a significant feature of the 2025 market: while privacy coins and exchange tokens regained momentum, AI-related assets experienced a substantial valuation reset.

Venice Sets Record for Largest Increase in 2026 So Far

Venice (VVV) set the record for the most intense price volatility in 2026 to date, skyrocketing by 1051.2% between January 1, 2026, and May 25, 2026. The token soared from $1.64 to $18.88 in just five months, becoming the most volatile token year-to-date. This surge was primarily due to adjustments in its token economics, including a reduction in token issuance and the introduction of a buyback and burn mechanism. Additionally, Venice formed a key partnership with OpenClaw, designating Venice AI as its primary model provider. At the same time, the growing demand for privacy-focused and "censorship-resistant" AI models further solidified its market position.

SkyAI (SKYAI) ranked second, with its price soaring 837.9% from $0.037 on December 31, 2025, to $0.35 on May 25, 2026. SKYAI capitalized on the trend of the "Model Context Protocol (MCP)." It successfully tested the MCP Hub designed to facilitate AI agent coordination, thus driving its price increase.

Siren (SIREN) ranked third with an increase of 647.3%, rising from $0.068 to $0.5. The integration of internet meme culture with AI utility benefited SIREN. Additionally, the support from Binance's Alpha platform, including early liquidity incentives and "Alpha Points" tasks, significantly boosted trading volume and attracted attention to the project.

DeXe (DEXE) ranked fourth, with a price increase from $3.15 to $17.56, reflecting a 458% rise. It successfully pivoted to the crossover of AI and DAO and introduced 18 new DAOs in March, propelling its price surge between March and April.

Unibase (UB) ranked fifth, with a year-to-date increase of 377.9%, rising from $0.035 to $0.17, primarily due to its positioning as a key "memory layer" for AI agents. The launch of UB perpetual contracts on OKX and the announcement of its agent service marketplace in late April were major catalysts for its price increase.

Unlike the volatility of 2025, which was dispersed across matured infrastructure tokens, the volatility in early 2026 was primarily concentrated in emerging, high beta AI assets. The comparison of these two periods reflects a broader shift in the behavior of the crypto market.
