ABTC, a U.S.-listed mining company, revealed in its May 7 financial report that it purchased over 10,000 new mining rigs from Bitmain for nearly $50 million. Notably, around 80% of the payment was made using 314 BTC as collateral instead of cash. The BTC was valued at $125,900 per coin, above the market price at the time of the transaction, with a two-year buyback agreement allowing ABTC to repurchase the BTC with cash if the price meets the agreed level. By the end of March 2026, ABTC had procured approximately $364 million worth of mining equipment from Bitmain, using only 3,090 BTC as collateral, with a fair value of about $210 million. This "BTC collateral + valuation lock + buyback option" structure highlights a cooling demand for mining rigs post-Bitcoin halving and increased buyer bargaining power.
