Altcoin market updates: SUI and Polkadot ETF Developments Fail to Draw Liquidity from XRP, ADA, and SOL

The global crypto market capitalization declined by 2.9% in the last 24 hours with market trends signaling how assets that were recently in profit are now facing liquidity outflows.

Last week, reports indicated that the US SEC was considering classifying XRP as a commodity as part of settlement talks in its long-running lawsuit with Ripple.

This fueled speculation about potential ETF approvals for XRP, LTC, ADA and HBAR, causing all four altcoins to experience double-digit gains before retracing over the weekend.

This week, new ETF developments have emerged with Canary Capital filing to list a SUI spot ETF — its sixth filing currently under SEC review. Similarly, NASDAQ has filed to list a

Polkadot ETF. These filings have driven short-term rallies in DOT (+7%) and SUI (+3%) over the last seven days.

However, a broader look at the market suggests that investors are rotating funds out of last week’s top gainers to chase fresh narratives.

This rotation is evident in the declining prices and volumes of XRP, SOL and Cardano, all of which are experiencing selling pressure in the past 24 hours.

XRP, SOL and Cardano market performance

• XRP: Trading at $2.23, down 0.6% in the last 24 hours, and 5.2% over the past week.
• Solana (SOL): Trading at $122.84, down 0.7% in the last 24 hours and 4.1% in the last week.
• Cardano (ADA): Trading at $0.6841, down 0.3% in the last 24 hours and 5.4% over the past week.

Chart of the day: Gainers vs. Losers 

The sharp decline in trading volumes for these altcoins suggests a shift in market sentiment, with traders reallocating capital toward assets with new catalysts such as the SUI and Polkadot ETF filings.

Gainers vs. Losers 

Top gainers today

• BubbleMaps (BMT): Up 68.7%, trading at $0.245.
• API3 (API3): Up 59.5%, trading at $0.9754.
• Dymention (DYM): Up 29.7%, trading at $0.423.

Top losers today

• Pi Network (PI): Down 14.2%, trading at $1.15.
• aixbt by Virtuals (AIXBT): Down 19.9%, trading at $0.09482.
• Vana (VANA): Down 14.2%, trading at $5.69.

Total crypto market cap tumbled toward $2.79 trillion on Tuesday , down 2.9% in the last 24 hours.

Trading volume also hit $84.95 billion, declining alongside major altcoins.

The current market trend highlights a shift in liquidity as traders move funds toward assets with fresh catalysts while exiting last week’s outperformers. ETF-related narratives remain dominant, with upcoming US Fed rate approvals potentially reshaping capital flows in the weeks ahead.

Paul Atkins' SEC chair confirmation delayed over pending financial disclosures

The confirmation of Paul Atkins, former SEC commissioner and Trump’s nominee for SEC chair, has been delayed due to pending financial disclosure paperwork from the White House, according to Semafor’s Eleanor Mueller.

The Senate Banking Committee, led by Tim Scott, is targeting March 27 for a confirmation hearing, but Atkins' complex financial holdings — particularly his ties to TAMKO Building Products LLC, a $1.2 billion roofing company connected to his wife’s family — have slowed the vetting process.

“No clarity yet on whether the committee has Atkins’ paperwork in hand, but either way, this is the most momentum we’ve seen so far,”

- Mueller wrote on X on Monday. 

Meanwhile, the Senate Banking Committee has scheduled a bipartisan meeting this Friday to discuss his nomination.

Despite the delays, Atkins remains on track for confirmation, following a similar timeline to previous SEC chairs, Gary Gensler and Jay Clayton, whose hearings also took place in March.
