The 20 millionth Bitcoin has been mined, leaving only about 1 million Bitcoins to reach the 21 million hard cap. Since February 24th, influenced by the conflict in Iran, Bitcoin has risen 8.09%, while gold has fallen 0.42% during the same period, indicating a trend of funds rotating from gold to digital assets. In the US market, the Coinbase premium and continuous inflows into BTC ETFs suggest that US buyers are driving this rally. Large single-day inflows occurred between February 24th and March 4th, followed by a slight net outflow on March 5th and 6th, before the inflow trend resumed in the last two days. MicroStrategy Preferred Stock (STRC) has seen a premium for four consecutive trading days accompanied by record trading volume. This premium is estimated to have driven approximately $130 million to $180 million specifically for Bitcoin purchases over the past two days, roughly equivalent to 40% of a strong ETF inflow day. When the price of STRC is above $100, MicroStrategy can efficiently raise funds through a market offering and use them to purchase Bitcoin.
