$BTC 😂 Investors in Eric Trump's mining company lost $500 million Eric Trump's mining company, American Bitcoin, went public with a valuation of $13.2 billion, holding only $270 million in BTC. Since then, the stock has plummeted 92%, and retail investors have lost around $500 million, according to Forbes. Meanwhile, the actual model turned out to be unprofitable: mining costs reach $90,000 per BTC, and most of the reserves are generated not through mining, but through the sale of shares and the purchase of Bitcoin.
