Market Downturn Overview

The late-year sell-off turned many high-beta tokens red, including BTC ($88,655, 24h volatility: 1.2%, Market cap: $1.76T, Vol. 24h: $35.61B) and ETH ($2,998, 24h volatility: 2.1%, Market cap: $359.82B, Vol. 24h: $20.21B). Looking at data from major aggregators, most of the poor performers have lost around 80% this year. This includes PEPE ($0.000004, 24h volatility: 1.7%, Market cap: $1.74B, Vol. 24h: $196.34M), once a meme-coin leader that has since lost 79% of its value, along with other high-profile altcoins.

In this analysis, we examine three major underperformers: Celestia (TIA), Optimism (OP), and Artificial Superintelligence Alliance (FET/ASI), reviewing how far each altcoin fell in 2025, what drove the moves, and how the market responded.

Celestia (TIA): -90%

TIA ($0.46, 24h volatility: 0.1%, Market cap: $396.47M, Vol. 24h: $31.27M), a proof-of-stake L1 blockchain optimized for app creation, lost almost 90% year-to-date. According to market data, it fell from about $5.5 at the start of 2025 to $0.46 near year-end.

Mostly, the drop was due to unlock and overhang dynamics. Celestia’s vesting and 2024-26 unlock cadence kept selling pressure steady in 2025. By summer, TIA was mainly viewed as a textbook post-airdrop unwind, with continuing emissions tied to thin liquidity.

Moreover, in August, Celestia Foundation disclosed it bought back 43.45 million TIA from Polychain (around $62.5 million at the time). The move was meant to steady the token supply, but instead spotlighted investor selling, prompting community backlash:

“This is a new level of grift tbh. Translation: We will now take $TIA tokens from one investor who was dumping and give it to another investor who will dump later on.”

Another major problem was weak fee capture and utilization optics. Independent on-chain analyses repeatedly highlighted very low data utilization and fee revenue (circa $60/day earlier in 2025). This reinforced a valuation vs. usage gap, with estimates suggesting the network could generate about $5.2 million in annual fee revenue if used correctly.

Optimism (OP): -84%

OP ($0.27, 24h volatility: 0.1%, Market cap: $528.68M, Vol. 24h: $54.94M), a popular layer-2 blockchain on top of Ethereum, lost 84.5% year-to-date. It fell from $2.06 at the start of 2025 to $0.27 in late December.

As with Celestia, persistent unlocks worked poorly for Optimism. OP faced recurring token unlocks throughout the year in late-May, late-April, and a scheduled Dec. 31 tranche of around $8.6 million. Each of those repeatedly added token supply during weak demand.

L2 competition was a significant headwind, too. Even as Optimism shipped fault-proofs and progressed on the Stage 1 decentralization path in 2024 and 2025, trading still reflected L2 sector fatigue and rotating liquidity. By September, media coverage framed OP as one of the L2 laggards, with the slide deepening into Q4.

Artificial Superintelligence Alliance (FET): -84%

ASI Alliance is a collaboration between three major blockchain-based AI projects: SingularityNET, Fetch.ai, and Ocean Protocol. In 2024, when it was founded, it was on the wave of AI hype. However, in 2025, it lost around 84% of its value, from $1.6 to about $0.2.

The first problems started in 2024. The multi-token ASI merger (FET, AGIX, OCEAN) did not go smoothly, creating operational noise. Several exchanges supported auto-conversions while certain platforms declined to facilitate migrations, adding uncertainty around flows.

In October 2025, Ocean Protocol exited the ASI Alliance, prompting governance disputes, legal threats, and a drop in the FET price around the time. The ASI board temporarily suspended the conversion bridge while seeking legal advice.

In addition, late-2025 risk-off spilled over into AI tokens. According to recent reports, AI is not the most profitable crypto narrative anymore. In fact, crypto AI coins have lost around 50% in price in 2025. The most profitable narrative has shifted back to real-world assets (RWA), which saw around +180% in gains.

The Bigger Altcoins Backdrop

Late-2025 macro and cross-market stress (tariff shocks, tight liquidity, tech-led risk aversion) broadly hit crypto, compounding token-specific supply overhangs. End-of-year reviews documented the wholesale risk-off turn and sharp liquidations across digital assets.
