Cash App vs Strike vs River: three top Bitcoin apps compared on fees, Lightning support, DCA features, and who each one is actually built for.
Cash App, Strike, and River are the three most popular apps for buying Bitcoin on your phone — and they could not be more different. Cash App is a payments super-app where Bitcoin is one feature among many. Strike is a Lightning-first app built for instant, near-zero-fee Bitcoin transfers. River is a Bitcoin-only brokerage focused on long-term holders, DCA, and clean self-custody flows.
Here is the direct comparison so you can pick the right one for how you actually use Bitcoin.
| Feature | Cash App | Strike | River |
|---|---|---|---|
| Bitcoin only | No (stocks, crypto, cash) | No (payments + BTC) | Yes |
| Buy Bitcoin | Yes | Yes | Yes |
| Lightning Network | Yes (limited) | Yes (core feature) | Yes |
| Recurring buys (DCA) | Yes | No | Yes |
| Self-custody withdrawal | Yes | Yes | Yes |
| Fee model | 1.75%–3% spread | ~0.3%–1.5% spread | 1.5% or 0% (River Pro) |
| US-only | Yes | No (35+ countries) | Yes |
| Earn Bitcoin | Yes (Boost) | No | No |
| FDIC/cash protection | Yes (FDIC insured USD) | No | No |
| Bitcoin reserves proof | No | Yes | Yes |
Cash App (/exchange/cash-app) is a Square (Block) product — a payments app that lets you send money to friends, get a debit card, buy stocks, and buy Bitcoin. More than 50 million people use Cash App regularly, the vast majority of whom use it for payments, not Bitcoin.
Cash App charges a spread (the difference between the buy and sell price), not an explicit commission. The spread is typically 1.75%–3% depending on transaction size and market conditions. There is also a fee for instant transactions (0.5%–1.75%). Larger buys get slightly better rates.
For someone buying $50–100 of Bitcoin per month, Cash App is convenient but expensive compared to Strike or River.
Cash App makes sense if you already use it for peer-to-peer payments and want to start buying a small amount of Bitcoin without downloading a separate app. The convenience is real — your USD, debit card, and Bitcoin are all in one place.
It is not the right tool if you are serious about minimizing fees, DCA large amounts, or optimizing your Bitcoin stack.
Strike (/exchange/strike) is built by Jack Mallers and is explicitly a Lightning-first Bitcoin app. Strike's core purpose is to make Bitcoin payments instant, global, and nearly free. Buying Bitcoin is a secondary feature, added to make Strike a complete product for everyday users.
Strike is the best app in the world for sending Bitcoin via Lightning:
For paying people internationally in Bitcoin, Strike is in a category of its own. A business owner paying a freelancer in Nigeria, the Philippines, or El Salvador can send money in seconds with no wire fees, no currency conversion delays, and no middlemen.
Strike does not have:
If your priority is automatic recurring Bitcoin accumulation, Strike is not the right tool — you will need to remember to buy manually.
Strike is for people who want to use Bitcoin as actual money — to pay people, receive payments, send remittances, or spend Bitcoin via Lightning. It is also good for one-time Bitcoin purchases at lower fees than Cash App.
For a freelancer getting paid in Bitcoin, a small business accepting Bitcoin payments, or someone sending money internationally, Strike is the best tool in this comparison.
River (/exchange/river) is the most Bitcoin-focused of the three. It is a Bitcoin-only brokerage — it does not offer other cryptocurrencies, does not try to be a payments app, and does not add features that distract from long-term Bitcoin accumulation.
Dollar-cost averaging: River has the best automatic recurring buy feature of any app in this comparison. You can set up daily, weekly, or monthly buys with precise control. River's recurring buy fees are 0% on River Pro plans and 1.5% on the standard plan — a significant advantage over Cash App and competitive with most exchanges.
Bitcoin-only: River does not list other cryptocurrencies. If you want to buy Bitcoin and nothing else, River's interface makes it impossible to accidentally buy a shitcoin during a moment of curiosity. This is a feature, not a limitation.
Proof of reserves: River publishes cryptographic proof of reserves. Your Bitcoin is actually held on your behalf — you can verify River holds enough Bitcoin to cover all customer balances.
Self-custody integration: River makes withdrawing Bitcoin to your own hardware wallet easy and clear. They actively encourage self-custody and have educational content for users ready to move off the platform.
Lightning Network: River supports Lightning deposits and withdrawals, making it easy to move Bitcoin to a Lightning wallet for spending.
River is for the long-term Bitcoin saver who wants to set up automatic recurring purchases, hold Bitcoin securely, and eventually move it to self-custody. It is the best of the three for building a Bitcoin position over time.
Strike wins for one-time purchases (0.3%–1.5% spread). River Pro wins for recurring DCA (0% fee). Cash App is consistently the most expensive of the three.
For anyone buying $100/month or more, the difference adds up quickly:
Cash App wins within the US for sending USD or Bitcoin between Cash App users (free, instant). Strike wins for sending Lightning payments to any wallet worldwide (not limited to Strike users).
If you and your friends all use Cash App, it is the most seamless for P2P transfers. If you are sending Bitcoin internationally or to people on different apps, Strike's Lightning integration is unbeatable.
River wins clearly. River Pro offers 0% on recurring buys, the interface is designed around DCA, and the Bitcoin-only focus eliminates distraction. Cash App also has recurring buys but at higher fees. Strike has no recurring buy feature at all.
Strike wins, and it is not close. Strike is available in 65+ countries. Cash App is US-only. River is US-only. If you want to pay a freelancer in the Philippines, send remittances to Mexico, or accept payments from customers in El Salvador, Strike is the only choice in this comparison.
Cash App wins for absolute beginners who are already on the app for other purposes. The barrier to buying your first Bitcoin on Cash App is low — you already have the app installed and your bank account linked.
River is the best choice for a beginner who is specifically trying to build a Bitcoin savings strategy and nothing else.
River — Bitcoin-only, self-custody-forward, proof of reserves, and no altcoin distraction. Strike is a close second for its Lightning-native philosophy.
Yes — and some serious Bitcoin holders do:
There is no reason to pick only one. The apps serve different functions, and having all three installed costs nothing.
Cash App is a legitimate company (Block, Inc.) and is as safe as any major exchange. However, like all exchanges, it is a custodial platform — you do not control the private keys. For long-term Bitcoin storage, withdraw to a hardware wallet. See our guide on Bitcoin cold storage.
No. As of 2026, Strike does not have an auto-DCA feature. You must buy manually each time. If you want automated recurring purchases, use River or Cash App.
No. River is US-only. For international users, Strike is the best of these three options, available in 65+ countries.
Strike has the most robust Lightning implementation — it is the core of the product. You can send to any Lightning address or BOLT11 invoice globally. Cash App supports Lightning via Cashtags but is more limited. River supports Lightning for receiving Bitcoin into the app.
Yes, all three support on-chain Bitcoin withdrawals to external addresses. River and Strike are the most self-custody-friendly in terms of UX and fees.
Use River if your goal is accumulating Bitcoin over time with low fees and a clear path to self-custody.
Use Strike if you want to send or receive Bitcoin payments — especially internationally — or want the cheapest Lightning experience.
Use Cash App if you are new to Bitcoin and already use the app, or if you want to send USD to friends who happen to also use Cash App.
For most long-term Bitcoin holders, River for DCA + Strike for payments is the ideal combination.
