How it works

PBIT would buy and sell call options on IBIT and hold bonds and cash. It would not hold bitcoin directly.

About a 10% floor

Each tranche's bought calls are struck at about 90% of IBIT's price, which sets an initial maximum loss of roughly 10% per tranche, before fees. Gains are capped.

Not guaranteed

The prospectus says protection is neither fixed nor guaranteed. The floor moves, fees reduce it, and investors can still lose money.
