CoinDesk 20 Index Performance Update: Internet Computer Leads Market Weakness with 1.6% Drop

On Thursday, May 21, 2026, the CoinDesk 20 Index faced downward pressure due to the weakness of major digital assets, led by Internet Computer (ICP). The index showed an overall retreat on this day, reflecting a contraction in investor sentiment across the cryptocurrency market.

As Bitcoin demand and ETF inflows weaken, Bitcoin is struggling below $80,000, which increases the risk of several months of sideways movement or a decline toward $65,000.

This downward trend follows the volatile market conditions observed in early May. Compared to the strong upward momentum shown on May 6, 2026, when the CoinDesk 20 Index surged by 2.5%, the current market is evaluated as having entered a clear correction phase.

Simultaneous Decline of Internet Computer and Hedera

Internet Computer (ICP) fell by 1.6%, serving as the biggest contributor to the index's decline on this day. Hedera (HBAR) also joined the list of declining assets, falling 1.3% compared to the closing price on Wednesday, May 20, 2026. The table below shows the detailed metrics of the assets that exhibited the most prominent declines within the index on this day.

• ['인터넷 컴퓨터(ICP): 1.6% 하락하며 지수 하락 주도', '헤데라(HBAR): 전일 대비 1.3% 하락하며 약세 동참', '코인데스크 20 지수: 주요 구성 자산의 부진으로 하방 압력 지속']

Bitcoin (BTC) price trends are exerting a strong influence on the index's constituent assets. As Bitcoin stagnates after failing to break the $80,000 mark, a simultaneous decline in liquidity and buying pressure in the altcoin market is being observed.

Market analysts warn that if the current lack of demand persists, Bitcoin could be pushed down to the $65,000 level. This is likely to act as an additional downside risk for other assets included in the CoinDesk 20 Index.

Technical Indicators and Market Structure Analysis

Despite the price decline, ICP's internal market indicators are showing positive aspects. Currently, ICP's market structure is not in an overheated state, which means that a gradual price adjustment is taking place rather than rapid liquidations.

The decrease in open interest and stable funding rates suggest that speculative forces in the market have been largely cleared out. While the long/short ratio remains optimistic, it is not at an extreme level, indicating that the market is in the process of finding a balance.

The key indicator for investors to watch during the second quarter of 2026 is whether Bitcoin maintains support at $65,000. Additionally, for ICP, breaking the $12 resistance level is expected to be a watershed moment for a future trend reversal.

In conclusion, the market movement on May 21, 2026, is the result of a combination of the absence of aggressive buying and technical adjustments of major assets. Investors need to prepare for the possibility of further sideways movement and closely monitor key support and resistance levels.
