News: Bitcoin is showing strong bullish momentum, nearing its all-time high, supported by positive institutional developments like corporate treasury adoption and the passage of a significant U.S. stimulus package. However, concerns about market valuation and potential inflation from the stimulus are present. Grayscale's halt in GBTC inflows due to a discount adds a note of caution, while potential increases in mining hardware supply from AMD could offer indirect support. Ether is showing relative weakness against Bitcoin.
