Bitcoin Leads Investor Portfolios as XRP Overtakes Solana for Third Spot 

Bybit’s H1 2025 survey shows Bitcoin’s slice of crypto portfolios climbed to 30.95% in May, up from 25.4% in November 2024. XRP allocations rose from 1.29% to 2.42%, overtaking Solana into the No. 3 slot, as Polymarket odds on a U.S. spot XRP ETF approval surged to 90%.

Crypto Portfolio Trends: Bitcoin Dominance and XRP Surge

Bybit’s May 2025 data marks Bitcoin’s highest portfolio share surge since spot ETFs launched in January 2024. The climb reflects strong demand from both retail and institutional buyers.

The Ether-to-Bitcoin ratio hit a low of 0.15 at the end of April before rebounding to 0.27 in May, meaning investors held about $4 in BTC for every $1 in ETH. That recovery follows a wave of staking yield cuts and major network upgrades that bolstered confidence in Ethereum’s long-term value.

XRP’s rise to 2.42% in May (up from 1.29% in November) pushed it past Solana into third place among portfolio holdings. Market chatter of a U.S. spot XRP ETF approval – Polymarket odds at 85 % and Bloomberg analysts at 95 % – fueled that jump.

Solana’s share slid as investors rotated toward “ETF-ready” coins, falling from 2.72% in November 2024 to 1.76% in May 2025. The drop underscores shifting sentiment away from memecoin-driven chains toward assets with clearer regulatory paths.

Corporate treasuries and ETFs now hold over 10% of Bitcoin’s supply. Public companies account for 3.97% (834,000 BTC) in treasuries, while U.S. spot ETFs hold 6.6% (1.39 million BTC). This institutional lock-up tightens available supply and may support future price floors.

Portfolio Realignment Drivers and Next Signals

Institutional investors poured over $38 billion into Bitcoin ETFs in H1 2025, according to the CME/Glassnode report, cementing BTC’s central role as a corporate reserve asset. Post-ETF launch volatility eased as markets shifted from speculative altcoins to BTC’s relative stability.

Glassnode details that after Bitcoin’s peak near $109 000, on-chain trading volume declined, driving investors toward staking and reserve strategies in BTC and ETH. This reduced volatility premium for altcoins bolstered BTC’s appeal as a core holding.

Looking ahead, traditional finance is eyeing integrated BTC and XRP products in DeFi and CeFi, while potential U.S. spot ETFs for Solana and other altcoins could trigger new portfolio shifts. Bitpanda forecasts that XRP’s cross-border payment utility may drive its price toward $5 by year-end if ETF approval and institutional uptake materialize.

Current allocation patterns reflect a maturing crypto market where institutional vehicles and regulatory clarity drive flows. With Bitcoin dominance holding above 60%, tokens like XRP (backed by ETF narratives) could emerge as new portfolio staples. Balanced strategies that mix core holdings, emerging altcoins, and DeFi yield products will define successful Web3 portfolios in 2025 and beyond.
