In a wide-ranging conversation with Bitcoin Magazine, the Strategy co-founder sketched out an "endgame" where his firm builds a trillion-dollar bitcoin balance sheet - and then uses that capital base to help reinvent the global credit system. "I think the endgame is we accumulate a trillion dollars worth of bitcoin and then we grow it 20, 30% a year," Saylor told Bitcoin for Corporations Managing Director George Mekhail. "The endgame is get to a trillion dollars of collateral growing 30% a year" At the core of Saylor's vision is scale. He believes Strategy - and other Bitcoin treasury companies likely to follow - can ultimately accumulate a trillion dollars worth of BTC.
