Hong Kong Desk Reads XWIN Japan's Stress Test: Why Bitcoin Kept Capital When SOL, ETH, XRP and BNB Did Not

HONG KONG — A six-month post-mortem published on May 11 by Tokyo-based research house XWIN Japan has begun circulating across Asia-Pacific trading desks this week, and it lands at an awkward moment for regional altcoin treasuries. The paper covers the October 2025 to April 2026 drawdown, the deepest stress test the major tokens have faced since the 2022 unwind, and its conclusion is unflattering for almost everything that is not Bitcoin.

XWIN puts Bitcoin's peak-to-trough loss at 52.5 percent, taking the asset from roughly $126,000 down to about $60,000. That headline number is grim in isolation, but inside Asia-Pacific allocation committees it reads as resilience. Solana surrendered 71.6 percent, dropping from $238 to $67. Ethereum and XRP each shed about 63 percent. Binance Coin gave back 59 percent. The recovery off the bottom rearranged the ranking only slightly. Solana clawed back 38 percent, Bitcoin 34.7 percent.

The structural story the Tokyo desk tells matters more to regional flows than the percentages. XWIN frames the move as "internal selection" rather than indiscriminate panic. Money did not exit the asset class so much as it concentrated. Bitcoin absorbed the capital that left altcoins, supported by exchange-traded fund subscriptions, corporate treasury accumulation and demand from allocators treating BTC as a geopolitical hedge. For Hong Kong family offices that began holding the spot ETF complex listed locally in 2024, the report effectively validates a thesis that has quietly become consensus across the harbour: Bitcoin is now traded as a macro instrument, not as a crypto position.

The Ethereum verdict is the section most likely to trouble Asia-Pacific issuers. Network telemetry held up through the entire drawdown — staking ratios climbed, Layer 2 throughput stayed firm, stablecoin settlement on Ethereum rails kept growing — and the token still collapsed from roughly $4,700 to under $1,800. Activity, in other words, did not defend price. That decoupling has implications for the wave of yen and won stablecoin projects routing through Ethereum and its rollups, where regional banks have been quietly underwriting infrastructure on the assumption that usage and valuation track together.

XWIN's read on XRP credits the regulatory and ETF narrative around cross-border payments, a thesis with particular weight along the Singapore-to-Manila remittance corridor. BNB held a little better thanks to ecosystem activity inside Binance, still a dominant venue for Southeast Asian retail.

Pricing as of this week shows the recovery is real but uneven. Bitcoin trades near $81,000, up about 11 percent over the past month. Ether sits near $2,300, a 4 percent gain. XRP is changing hands around $1.45 after a 7.5 percent monthly rise. Solana has led the bounce, climbing about 12 percent on the week to roughly $95.

For regional allocators, the XWIN paper formalises something Tokyo and Hong Kong trading desks have been pricing for months. When liquidity contracts across Asian hours, the bid that returns first is the Bitcoin bid.
