Cash App charges no fees when you buy or sell bitcoin.
However, Cash App may apply an exchange rate based on the size of your transaction and a spread determined by volatility across U.S. exchanges.
Bitcoin purchases made through Cash App are carried out at a mid-market rate that is determined by volatility and exchange price.
The spread is the difference between the current “bid” and “ask” prices and may be different from when you bought or sold.
You can monitor bitcoin’s price by tapping the available balance on your Cash App home screen (shows “Cash & BTC” if your account balance is $0) and swiping left.
