Square Cash is testing cryptocurrency support by letting a small number of users buy and sell Bitcoin directly in the app
Some customers of Square's Cash app have gotten a surprise in the past week. — The app, which is used for payments between friends and is a competitor to Venmo …
Context & Ripple Effects
In late 2017, Square's Cash app — a peer-to-peer payments rival to Venmo — quietly began letting a small group of users buy and sell Bitcoin directly inside the app, making it one of the first mainstream consumer payment apps to embed crypto trading rather than route users to an exchange.
The experiment scaled fast: by early 2018 Jack Dorsey said almost all Cash App users could trade Bitcoin, though four states including New York remained excluded on licensing grounds ([[a:926316]]), and by August 2018 Square had extended the feature to all 50 states ([[a:932381]]). The bet paid off — by Q1 2020 Bitcoin transactions generated $306M of the app's $528M revenue, overtaking its fiat business for the first time ([[a:953409]]) — and Square went on to test free stock trading in the same app ([[a:945839]]).
First-order effects
- A small cohort of Cash App users can now buy and sell Bitcoin without leaving a payments app they already use for friend-to-peer transfers, collapsing the separate exchange-account step.
- Square gains a direct transaction-fee revenue line on every trade, monetizing its existing user base rather than paying customer-acquisition costs to reach crypto buyers.
Second-order effects
- Venmo, named as Cash's closest competitor, faces pressure to match embedded crypto trading or cede the 'one app for money' position among shared demographics.
- Once Bitcoin proves out, adjacent asset classes follow — Square's later testing of free stock trades in Cash shows the crypto feature functioning as a template for turning the app into a multi-asset retail trading surface.
Third-order effects
- State-by-state money-transmission and licensing rules become the gating factor for national rollouts, as seen in the four-state exclusion that persisted months after most users got access — pushing consumer fintechs toward either slow state clearance or federal regulatory clarity.
- If the pattern holds, P2P payment apps consolidate into consumer financial super-apps where trading, spending (via Cash cards) and transfers live in one balance — shifting competitive gravity from payment volume to assets under management.
The trend: Consumer payment apps are absorbing exchange and brokerage functions, turning peer-to-peer wallets into full retail trading platforms with Bitcoin as the wedge.
