Twenty One Capital (XXI) CEO Jack Mallers said on Tuesday that while Bitcoin (BTC) is “perfect money,” but borrowing against it is getting expensive. He added that Strategy’s (MSTR) move from 0% borrowing to double-digit rates reflects a tightening Bitcoin lending market.
Speaking at the Bitcoin 2026 conference in a panel discussion, Mallers explained that borrowing against Bitcoin remained expensive because investors did not want to lose exposure to an asset that could deliver strong long-term returns. Capital providers need to be meaningful.
According to Jack Mallers, Saylor's current interest rates accurately represent the whole Bitcoin lending market. He added that investors expect large returns when lending cash, given the opportunity cost of not investing in high-growth assets such as Bitcoin, Nvidia (NVDA), AI firms, and luxury real estate.
The Twenty One Capital CEO said that the Bitcoin lending market was shaped by “supply and demand,” not just the quality of collateral. Bitcoin is regarded as high-quality collateral, but lenders compare its returns with those of other opportunities, including government bonds and equities. Companies that used to borrow at near-zero cost now face double-digit rates, he said, pointing to a shift in borrowing conditions across the market.
“Michael Saylor used to be borrowing money at 0% do you think that he got sick that and preferred 11%-12%-13%? Probably not, right? He's doing it because there he ran out of people willing to give him money at 0%, and so if you're going to ask someone in the crowd, hey, don't buy bitcoin, buy stretch.”

Mallers said that while cheaper financing could emerge over time as larger financial institutions expand into Bitcoin markets, the current environment shows that such capital has not yet arrived at scale. “We are just not there yet,” he said, describing borrowing costs as structurally elevated for now.
Some industry players criticized Mallers' comments, saying Mallers didn't take into account that "$STRC is perpetual" and has no maturity date and no fixed repayment schedule, which could justify a different cost structure than traditional Bitcoin-backed lending.

Mallers subsequently explained that it was “not a diss” to Saylor but rather a general comment about capital costs and market structure. Bitcoin markets are becoming more influenced by traditional financial dynamics, with borrowing, lending, and capital allocation reflecting more mature market circumstances rather than early-cycle behavior, he noted.
