The sharp decline in the supply of Bitcoin on the exchange may indicate that prices are about to soar due to a "supply shock". This phenomenon occurs when strong buying demand clashes with the reduced availability of Bitcoin supply.

This trend usually indicates that investor confidence is increasing and shifting towards long-term holding. For example, BTC is often transferred to cold wallets or self-hosted wallets, thereby reducing the liquidity supply available for trading.

Whales usually withdraw after buying BTC, indicating that they are accumulating funds. As the available BTC for sale decreases, short-term selling pressure will ease.

Bitcoin Recovers Due to "Strong Institutional Demand"

Despite a slight decline of 2.85% in Bitcoin over the past two days, Bitcoin has remained at the key psychological support level of $100,000 since May 28.

Theo Lau, the founder of Focusw3b, stated that the resilience of Bitcoin breaking through the $100,000 mark is supported by "strong institutional demand" and "reduced" supply.

This demand is most clearly reflected in the capital inflow of spot Bitcoin ETFs, which have recorded capital inflows for 15 consecutive days.

According to a report by SoSoValue, this wave of growth began on June 9, with inflows exceeding $386 million, and continued into Monday, adding another $102 million. In the past 15 days, over $4.7 billion has flowed into spot Bitcoin ETFs.

Maintaining the psychological support level of 100,000 USD is crucial for ensuring the growth momentum of Bitcoin and avoiding a significant decline.

CoinGlass data shows that a potential pullback below $100,000 will trigger the liquidation of leveraged long positions across all exchanges worth over $6.42 billion.
