If you have decided to buy Bitcoin and you want to do it through a platform that takes Bitcoin seriously – not one that also sells Dogecoin and NFTs – you are looking at a short list. River, Strike, and Swan are three of the best Bitcoin-only platforms available in the United States.
I have used all three. Here is an honest breakdown of each one, what they are good at, where they fall short, and who each one is best suited for.
Why Bitcoin-Only Platforms Are Different
Most popular exchanges – Coinbase, Kraken, Binance – are crypto exchanges. They support hundreds or thousands of tokens. Their business model depends on listing new coins, collecting trading fees across all of them, and keeping you engaged with the broader crypto market.
Bitcoin-only platforms have made a deliberate choice. They believe Bitcoin is the only digital asset worth building infrastructure around. That focus shows in their products – deeper Bitcoin features, stronger security practices, and a customer base that is serious about long-term accumulation rather than speculative trading.
If you are buying Bitcoin to hold for years, a Bitcoin-only platform is the right environment.
River: Best Overall for Buying and Holding
River is my top pick among the three for someone whose goal is to accumulate Bitcoin and hold it securely over the long term.
Proof of reserves
River publishes proof of reserves – cryptographic verification that they actually hold the Bitcoin they claim to hold on behalf of customers. This is not standard practice in the industry. Most exchanges ask you to trust their word. River lets you verify. For a platform holding your Bitcoin, that transparency matters.
Force Shield security
River offers a feature called Force Shield that adds an extra layer of protection to your account. It is designed to prevent unauthorized withdrawals even if someone gains access to your login credentials. For long-term holders who are not moving Bitcoin frequently, this kind of security feature is exactly what you want.
Yield on cash balances
River offers approximately 3.3 percent yield on USD cash balances, paid in Bitcoin. Here is what makes this particularly interesting: even limit orders that have not executed yet earn the yield. If you set a limit order to buy Bitcoin at a specific price and it has not triggered yet, that cash is still earning yield in the meantime – paid in Bitcoin. That is a feature I have not seen elsewhere.
Fees
River’s fees are higher than some competitors. That is the honest tradeoff for the security, transparency, and features they offer. For someone accumulating Bitcoin over years and prioritizing security over the lowest possible fee, the premium is worth it. For someone making very small frequent purchases, the fees may add up more than you want.
Who River is for
Serious long-term Bitcoin accumulators who prioritize security, proof of reserves, and want their cash earning yield while they wait for limit orders to fill. River is not the flashiest platform but it is one of the most trustworthy.
Strike: Easiest to Use, Watch the Spreads
Strike is the most user-friendly of the three. The app is clean, setup is fast, and buying Bitcoin takes about thirty seconds. It also has features that go beyond a simple exchange.
Lightning Network payments
Strike is built on the Bitcoin Lightning Network, which enables instant, near-zero fee Bitcoin transactions. You can send Bitcoin to other Strike users instantly and for free. You can also pay Lightning invoices directly from your Strike balance. For anyone interested in actually using Bitcoin as a payment network rather than just holding it, Strike is the best platform for that.
Bill pay and cash transfers
Strike lets you pay bills directly and send money to other Strike users. These features extend the platform beyond a simple exchange into something closer to a full financial tool built on Bitcoin rails.
Bitcoin-backed loans
Strike offers the ability to borrow against your Bitcoin holdings. The concept is sound – you get liquidity without selling your Bitcoin and triggering a taxable event. However, the interest rates Strike charges are high compared to alternatives. If you are interested in Bitcoin-backed borrowing, look at Morpho on Coinbase before committing to Strike’s rates. The rates are more competitive there.
Spreads
This is Strike’s biggest weakness for pure accumulation. Strike makes money on the spread between the buy and sell price rather than a flat fee. In practice, if Bitcoin is trading at $80,000, Strike may execute your purchase at $81,000. On a $500 purchase that is a $500 to $510 effective cost – not catastrophic, but it adds up over time and it is less transparent than a flat fee structure. Pay attention to what price you are actually getting, not just the current market price.
Who Strike is for
People who want the easiest possible on-ramp to Bitcoin, plan to use Lightning Network payments, or want to send Bitcoin to friends and family on the same platform. Less ideal as your primary DCA vehicle if you are cost-conscious about fees and spreads.
Swan: Solid for Recurring Purchases, With a Unique IRA Option
Swan was built specifically around the dollar-cost averaging use case. The entire product is designed around helping you buy Bitcoin automatically on a recurring schedule and hold it for the long term.
Recurring purchases
Swan makes setting up automatic recurring Bitcoin purchases straightforward. You pick an amount, pick a frequency, and Swan handles the rest. This is also available on River and Strike, but Swan built their entire product philosophy around this use case from day one.
Bitcoin IRA
Swan offers a Bitcoin IRA – a self-directed IRA that holds actual Bitcoin rather than a Bitcoin ETF. This is genuinely unique. If you want real Bitcoin exposure inside a tax-advantaged retirement account and are not satisfied with an ETF like FBTC, Swan’s Bitcoin IRA is one of the few ways to do it. The setup is more involved and the fees are higher than a standard IRA, but for someone who wants actual Bitcoin in a retirement account, it is worth researching.
Overall value for small DCA
For small recurring purchases – say $50 to $200 per week – Swan is the least attractive of the three. The fee structure and minimums make it better suited for larger recurring purchases. River handles small DCA better and with stronger security features. Swan becomes more compelling as your purchase size grows or if the Bitcoin IRA is relevant to your situation.
Who Swan is for
People making larger recurring purchases who want a platform built purely around long-term accumulation, or anyone interested in holding actual Bitcoin inside a self-directed IRA rather than an ETF.
Side by Side

River: publishes proof of reserves, Force Shield protection. Strike: standard security, no proof of reserves. Swan: solid security, no proof of reserves.
Fees
River: flat fee, higher than some competitors, fully transparent. Strike: spread-based pricing, less transparent, can be significant on larger purchases. Swan: fee structure favors larger purchases, less competitive for small amounts.
Yield on cash
River: approximately 3.3 percent yield on USD balances paid in Bitcoin, applies even to pending limit orders. Strike: no equivalent feature. Swan: no equivalent feature.
Lightning Network
Strike: built on Lightning, best Lightning experience of the three. River: supports Lightning. Swan: limited Lightning support.
Bitcoin IRA
Swan: yes, holds actual Bitcoin. River: no. Strike: no.
Bitcoin-backed loans
Strike: yes, but rates are high – compare to Morpho on Coinbase first. River: no. Swan: no.
Which One Should You Use
If your goal is to buy Bitcoin consistently and hold it securely for the long term, River is the best overall choice. The proof of reserves, Force Shield security, and yield on cash balances make it the most complete platform for serious accumulators. The fees are higher but the tradeoffs are worth it.
If you want the easiest possible experience and plan to use Bitcoin for Lightning payments or bill pay, Strike gets the job done. Watch the spreads and understand what you are actually paying.
If you are making larger recurring purchases or want to explore holding actual Bitcoin inside a retirement account, Swan is worth a serious look – specifically for the Bitcoin IRA feature.
Most people are best served starting with River, getting comfortable with how it works, and exploring Swan’s IRA option once they understand what they are doing and why.
None of these platforms are wrong choices. All three are Bitcoin-only, all three take security seriously, and all three are significantly better than leaving Bitcoin on a general exchange that treats it as one token among thousands.
Frequently Asked Questions
What is the best Bitcoin-only exchange?
For buying and holding Bitcoin long term, River is the strongest overall choice. It publishes proof of reserves, offers Force Shield security, and pays approximately 3.3 percent yield on USD balances in Bitcoin – including on pending limit orders. Strike is the easiest to use but has spread-based pricing that can be costly. Swan is best for larger recurring purchases or if you want a Bitcoin IRA holding actual Bitcoin.
What is proof of reserves and why does it matter?
Proof of reserves is cryptographic verification that an exchange actually holds the Bitcoin it claims to hold on behalf of customers. FTX collapsed in 2022 with a massive shortfall between what customers thought they owned and what the exchange actually held. River publishes proof of reserves so customers can verify their holdings independently rather than taking the exchange’s word for it.
What is a Bitcoin IRA?
A Bitcoin IRA is a self-directed individual retirement account that holds actual Bitcoin rather than a Bitcoin ETF. Swan offers one of the most accessible versions. It allows you to hold real Bitcoin inside a tax-advantaged retirement account – gains grow tax-deferred in a Traditional IRA or tax-free in a Roth structure. Setup is more involved and fees are higher than a standard IRA, but it is one of the few ways to hold actual Bitcoin in a retirement account.
What is the Lightning Network?
The Lightning Network is a payment layer built on top of Bitcoin that enables instant, near-zero fee transactions. While regular Bitcoin transactions can take minutes and cost a few dollars in fees, Lightning payments settle in seconds for fractions of a cent. Strike is built on Lightning and offers the best Lightning payment experience of the three platforms compared here.
Is Strike safe to use?
Strike is a legitimate, regulated platform and is safe to use for buying Bitcoin. The main thing to watch is the spread-based pricing – the price you pay for Bitcoin may be higher than the current market price. For long-term holding, consider moving Bitcoin to a hardware wallet like Trezor after purchase rather than leaving large amounts on any exchange.
