Analysis: The four major DAT giants have increased their holdings for the first time in six months, helping BTC break through the $70300 pressure level The New Fire Research Institute, a subsidiary of New Fire Technology (1611. hk), has published an analysis stating that BTC has successfully surpassed the key resistance level of $70300 in volume, and the main funds have maintained a stable net inflow trend, effectively cleaning up the floating funds that had previously fluctuated in the $60000 range, and successfully establishing a new price center. In the past six months, four leading DAT companies, Strategy, MARA, BitMine, and SharpLink, have intensively increased their positions for the first time since March. The latest data shows that these institutions hold 5.5% of the total supply of BTC. This institutional level 'resonance' not only stabilizes the price center of gravity after the breakthrough, but also marks the market's entry into a potential upward channel of oscillation. At the same time, the traditional financial system is laying the "compliance red carpet" for Bitcoin at an unprecedented speed. The US CPI data for February met expectations, and the market has fully priced in the expectation of keeping interest rates unchanged in March. The elimination of macro uncertainty provides a clear observation window for large funds to enter the market. From the upcoming announcement of the first batch of stablecoin licenses in Hong Kong to the official entry of Wells Fargo into the stablecoin territory through the WFUSD trademark, traditional financial giants have transformed from "observers" to "infrastructure developers". Especially VanEck's push to include digital asset ETFs in corporate 401K retirement plans, as well as Kraken's partnership with NASDAQ for xStocks tokenized stock trading volume, are driving the gradual integration of cryptocurrency assets with traditional finance. In addition, Coinbase's sustained positive premium is a direct proof of the stable purchasing power of US institutions.
