Augustine Fan, the head of SignalPlus, analyzed that the recent sell-off of Bitcoin was mainly triggered by multi-strategy hedge fund trading that dominates the macro market. These trades involve arbitrage, long and short positions, and leveraged operations, aimed at maximizing returns across asset classes. In the Bitcoin market, a common multi-strategy trading method is basis trading, which profits from the price difference by buying spot Bitcoin (usually through ETFs) and shorting Bitcoin futures. However, when the price difference narrows or the market changes, the profits from basis trading decrease, leading to capital exiting positions and a concentrated sell-off of Bitcoin and ETF shares. Fan pointed out that this liquidation pressure amplified the sell-off over the past week, particularly against the backdrop of increased volatility related to tariffs. Nevertheless, the sentiment of "buying the dip" still exists in the market. Fan stated that stock valuations outside of major blue-chip companies remain relatively stable compared to historical averages, and hard economic data may perform better than the rapid deterioration of soft data. Therefore, the market is generally considered to still be a "buying the dip" market, and it is expected to gradually digest the impact of tariff volatility.
