Bitcoin Exchange Free
From the end of 2017, Cash App started allowing users to use their balances to buy and sell bitcoin. While there was no fee for this service when it was first introduced, in late 2019, Cash App began charging users fees of as much as 1.76% on bitcoin purchases. This is one of Cash App's most profitable services. In addition to the service fee, there is generally a 1% to 4% difference in what bitcoin exchanges and individuals pay for bitcoin. Cash App factors these differences into the prices it offers its users, thereby generating additional revenue on the exchanges it facilitates.3
For example, Cash App might buy a bitcoin from one user for $9,900 and sell it to another for $10,000, making $100 in revenue. Cash App calculates this price difference based on fluctuations in the value of bitcoin.
