Why corporate Bitcoin hoarding could trigger the next big crypto selloff

By July 2025 public companies were sitting on 917,853 BTC and one of them, Saylor’s Strategy, holds 607,700 of that, it about 2.9% of all bitcoin. A year ago the total corporate stash was just 325,400 BTC, so the growth has been insane.

A lot of these new players aren’t just diversifying like Tesla or Coinbase. Some are miners holding instead of selling, but a growing chunk are basically quasi-ETFs whose whole business is piling up BTC per share and even branching into ETH or SOL.

They raise money with convertible bonds, which means if things go south they might have to dump coins to cover debt. That’s where the domino risk comes in. Even if the first big debt maturities aren’t until 2029, a single panic sell could shake confidence and spark a chain reaction long before then.

The irony is bitcoin was born after the 2008 crash to get away from Wall Street’s risky games, and now those same mechanics could end up being the weak spot in the market.
