According to @EmberCN, BitMine (BMNR) began accumulating ETH on July 9 and still held an ETH position as of Aug 17 based on the company’s disclosed purchase quantities and prices compiled in the post (source: @EmberCN on X, Aug 20, 2025). According to @EmberCN, SharpLink Gaming has also been buying ETH over the past two months, and the post estimates a weighted-average cost basis for its ETH treasury from its announced buy quantities and prices (source: @EmberCN on X, Aug 20, 2025). According to @EmberCN, traders are watching the compiled cost-basis levels as potential support during the current ETH pullback (source: @EmberCN on X, Aug 20, 2025). According to @EmberCN, monitoring ETH price reaction near those cited cost levels and any new purchase disclosures from both companies is a key trading focus for ETH spot, derivatives, and related equities (source: @EmberCN on X, Aug 20, 2025).
