Bitcoin is a digital currency which operates free of any central control or the oversight of banks or governments. Instead it relies on peer-to-peer software and cryptography. A public ledger records all bitcoin transactions and copies are held on servers around the world.

As the cryptocurrency sell-off intensifies, make sure you're making the right choice between buying Bitcoin directly or a Bitcoin exchange-traded fund (ETF).

If you’re wondering what happens if Bitcoin crashes, experts say the fallout could ripple beyond crypto and impact everyday investors too.

ProShares Bitcoin ETF is structurally disadvantaged vs. spot Bitcoin ETFs, with persistent underperformance due to futures costs and a high expense ratio. Learn more about BITO ETF here.
