Onramp vs Cash App: An Honest Comparison for Bitcoin Holders

Onramp and Cash App both let you buy and hold Bitcoin in the United States, but they are built for fundamentally different holders. Cash App is a consumer banking and payments app from Block where Bitcoin is one feature alongside peer-to-peer payments, a debit card, stock investing, and direct deposit. Onramp is a Bitcoin-only financial platform built on a Multi-Institution Custody foundation, spanning custody, brokerage, an earn account, the Onramp Card, Bitcoin-backed loans through Arch Lending, an optional Bitcoin IRA, integrated inheritance, and the Onramp Terminal, structured across three tiers that begin with a free Finance account and scale to institutional-grade custody. Here is how they actually compare.

Key Takeaways:

• Cash App is excellent at consumer-grade Bitcoin buying integrated with day-to-day banking. Zero fees on recurring buys, direct deposit, and one-time purchases over $2,000, though one-time buys under $2,000 carry a tiered fee that can reach 2% to 3% on smaller amounts, which makes Onramp's flat 0.85% the cheaper option for everyday small purchases. Strong Lightning Network integration, the Cash App Card with overdraft, and Bitkey integration for users who want to graduate into self-custody. The platform caps Bitcoin movement off it at $10K/day and $25K/week, plus a $999 rolling-seven-day Lightning send limit, which is a real friction for holders building serious positions.
• Onramp is a Bitcoin-only financial platform built on a custody foundation it has operated since 2023. It spans three tiers: a free Finance account ($0/month) with Bitcoin brokerage at 0.85%, an earn account paying up to 3% (Onramp-funded rewards, not interest), the Onramp Card with 0.5% cash-back convertible to Bitcoin, Bitcoin-backed loans through Arch Lending, custody at BitGo Trust with Lloyd's of London insurance, and the Onramp Terminal; Onramp Core ($250/month), which adds Multi-Institution Custody, an included Bitcoin IRA, integrated inheritance, individual-vault Proof of Reserves, and Lloyd's coverage up to $100 million per incident; and Onramp Private, which adds dedicated account management and Virtual Family Office access. You enter free, and the platform scales with your position.
• The structural difference is that Onramp built its custody foundation first. Multi-Institution Custody has been live since 2023, and the financial services were added on top of that architecture. Every consumer Bitcoin app, including Cash App, built financial services first and treats custody as a downstream consideration. Onramp clients have a defined upgrade path to Onramp Core for Multi-Institution Custody, an included Bitcoin IRA, integrated inheritance, and higher-coverage insurance.
• The right platform depends on what you are actually doing with Bitcoin. For day-to-day spending, Lightning payments, and small recurring buys, Cash App is built for that flow. For a platform built to custody and grow a Bitcoin position over decades, with a defined path from a free account to institutional-grade custody, Onramp is the more appropriate choice. The two platforms are not competing on the same dimension.

The Fundamental Difference

Cash App is a consumer banking and payments app that happens to support Bitcoin natively and well. Onramp is a Bitcoin-only financial platform built on Multi-Institution Custody architecture. Both starting points are legitimate, and they produce two very different products.

Cash App's primary product is the cash account, the peer-to-peer payments, the Cash App Card, and the broader banking experience. Bitcoin is one feature in that surface. The design choices reflect the consumer audience: friendly mobile UX, fast onboarding, and integration with the rest of someone's day-to-day money flow. For a casual buyer, that integration is genuinely useful.

Onramp was built on a custody foundation it has operated since 2023. The brokerage, the earn account, the Onramp Card, the loans through Arch Lending, the Onramp Terminal, and the tier structure that runs from a free Finance account up to Multi-Institution Custody at Onramp Core are all designed to serve a holder whose Bitcoin position is the center of the financial relationship. The Bitcoin-only focus is the value proposition for holders who view Bitcoin as fundamentally different from the rest of their day-to-day money.

The strategic distinction matters. Most consumer Bitcoin platforms built brokerage and a cash account first, then added custody after the fact. Onramp went the other way: custody was the starting product, and the financial services were built on top to give clients a complete platform anchored by a custody architecture that no consumer Bitcoin app currently matches. Both models are legitimate. They produce two different products with different strengths.

Cash App at a Glance

Cash App is the consumer financial app of Block, Inc. (formerly Square), one of the largest Bitcoin-aligned public companies in the world. The product combines banking, peer-to-peer payments, the Cash App Card, direct deposit, stock investing, and Bitcoin buying in a single mobile interface. The company's compliance posture and disclosure requirements as a public company create real accountability that smaller or offshore apps cannot match.

Bitcoin features as of 2026:

• Zero fees on Bitcoin purchases above $2,000, on recurring buys (Auto Invest), on Round-Ups, and on direct-deposit-to-bitcoin conversions
• One-time purchases under $2,000 carry a tiered service fee that is higher in percentage terms the smaller the purchase (historically ranging from roughly 1.5% to 3% on smaller buys, easing toward 0.75% to 1% near the $2,000 threshold), plus a 0% to 0.75% spread depending on market conditions, shown on the confirmation screen before you buy
• Lightning Network send and receive, with a 0.9% processing fee on Lightning payments funded from a Cash balance
• On-chain Bitcoin withdrawal limits of $10,000 per day and $25,000 per week for eligible customers, plus a Lightning send cap of $999 per rolling seven-day period
• Bitkey integration, allowing users to graduate to Block's self-custody hardware wallet
• Proof of Reserves published at the aggregate platform level, attesting that customer Bitcoin is held 1:1 in full reserve across all customer holdings combined

Broader features: the Cash App Card with overdraft, Cash App Savings up to 3.25% (requires a Cash App Card plus $300/month direct deposit), Cash App Investing for stocks, P2P payments, bill pay, and ATM access.

For a casual Bitcoin buyer already managing their day-to-day money through Cash App, the friction of buying and holding Bitcoin is genuinely lower than at most platforms. The product is excellent for what it is designed to do. For holders who want Bitcoin specifically, the consumer-first orientation, the single-custodian model, the absence of loans, an IRA, and inheritance, and the withdrawal limits are tradeoffs worth examining. Those limits cap how much Bitcoin you can move off Cash App at $10K/day and $25K/week, and for holders building positions in the five and six figures, they can take weeks to clear if you want to move a position into a different custody arrangement.

Onramp at a Glance

Onramp is a comprehensive Bitcoin financial platform structured across three tiers, all built on a custody foundation Onramp has operated since 2023. You enter through a free Finance account and the platform scales as your Bitcoin position grows.

The free entry point: Onramp Finance ($0/month). The Finance tier is free forever and consolidates the core of a Bitcoin financial life on one platform, matching what Cash App does on buying and holding while adding surfaces Cash App lacks:

• Bitcoin brokerage at 0.85% in all 50 US states, with limit orders, ACH funding, and recurring buys for dollar-cost-averaging. Brokerage is also available internationally in many countries.
• Earn account paying up to 3% (Onramp-funded rewards from corporate revenue, eligibility tied to completing at least one bitcoin trade per month, not interest or yield). Earn rewards are not currently available to clients in New York, but a Finance account can still be opened there.
• The Onramp Card, a Visa debit card with 0.5% cash-back paid in dollars and convertible to Bitcoin in one click, accepted anywhere Visa is accepted
• Bitcoin-backed loans through Arch Lending, where Arch is the lender and holds the Bitcoin collateral with Anchorage, a regulated qualified custodian. Bitcoin-only collateral (Arch supports other digital assets but Onramp does not), up to 50% loan-to-value, fixed rates for the loan term, no rehypothecation, and an optional deferred interest payment structure where interest is paid at the end of the loan rather than monthly
• Custody at BitGo Trust, a regulated qualified custodian under South Dakota and New York trust banking law and one of the most established Bitcoin custodians in the United States, with Lloyd's of London insurance
• The Onramp Terminal: a Bitcoin-only research and data platform with thousands of interactive charts covering on-chain metrics, macro overlays, miner economics, ETF flows, and derivatives positioning, included free with every account
• Direct human client service through Onramp Client Services
• Bitcoin IRA available as a $100/month add-on at the Finance tier (custodied at BitGo Trust)

The custody upgrade: Onramp Core ($250/month). Core adds Multi-Institution Custody (MIC), where three independent regulated institutions (Onramp, BitGo Trust, and CoinCover) each hold one key in a 2-of-3 architecture. Transactions are initiated from the client's Onramp account, and two of three institutions work at the client's direction to execute. No single institution, including Onramp itself, can move client Bitcoin without the client's direction. Core also includes a Bitcoin IRA in a Multi-Institution Custody vault, integrated inheritance planning with a built-in beneficiary designation, Lloyd's of London coverage up to $100 million per incident, Guardian Plus security services, real-time Proof of Reserves at the individual vault level, brokerage at 0.65%, earn rewards up to 4%, and 1% cash-back on the Onramp Card.

The top tier: Onramp Private (0.04% of AUM per month). Private adds a dedicated account manager, reduced trading fees, Virtual Family Office access for estate and dynasty trust planning, brokerage at 0.32%, earn rewards up to 5%, and 1.5% cash-back.

The thesis: Bitcoin is savings, dollars are working capital. Onramp is built around a specific framing: dollars in the platform are working capital, not savings. They earn rewards, enable spending through the Onramp Card, facilitate borrowing through Arch Lending, and ultimately flow into Bitcoin accumulation. Bitcoin in custody is the savings account. Everything else is a tool to help clients accumulate more of it. Clients typically start on Finance and upgrade to Core when their Bitcoin position grows to the point where Multi-Institution Custody, an included IRA, integrated inheritance, and the higher-coverage Lloyd's policy matter more.

The Custody Foundation: Why It Matters

The strongest structural argument for Onramp over Cash App is also the least obvious one. Onramp built its custody architecture first and added the financial services on top. Cash App, like every consumer Bitcoin app, built consumer banking first and treats Bitcoin custody as a downstream consideration.

Cash App holds your Bitcoin in a single corporate custodial structure, not a qualified trust. Block publishes Proof of Reserves at the aggregate platform level, attesting that customer Bitcoin is held 1:1 across all customer holdings combined, which is genuinely better than the disclosure regime at most exchanges. But it remains a single custodian, and the entire trust assumption rests on Block remaining solvent, secure, and operational. Per Cash App's own legal disclosures, Bitcoin holdings are not FDIC insured, not SIPC protected, not backed by the US government, and not privately insured by the company. There is no path to a structurally different custody model inside the product.

Onramp's free Finance tier holds your Bitcoin at BitGo Trust, a regulated qualified custodian under South Dakota and New York trust banking law and one of the most established Bitcoin custodians in the United States. BitGo Trust holds Finance client Bitcoin in segregated structures with Lloyd's of London insurance. BitGo Trust is also one of the three independent keyholders in Onramp's Multi-Institution Custody architecture, which clients access through Onramp Core.

Onramp Core distributes key control across three independent regulated institutions. Onramp, BitGo Trust, and CoinCover each hold one key in a 2-of-3 multisig structure. Transactions are initiated from the client's Onramp account, and two of three institutions work at the client's direction to execute. No single institution, including Onramp itself, can move client Bitcoin without the client's direction. The MIC architecture is backed by Lloyd's of London coverage up to $100 million per incident, segregated and client-titled vaults that are off Onramp's balance sheet and bankruptcy-remote, real-time Proof of Reserves at the individual vault level (a structural distinction from aggregate Proof of Reserves, which is published across the whole platform rather than at any individual client's vault), and integrated inheritance planning.

The structural significance of distributed custody is not theoretical. Onramp's research on the Proof of Reserves Illusion documents twelve major Bitcoin custody failures between 2011 and 2025, every one of which was a single-custodian arrangement. Multi-Institution Custody at the consumer-platform level is also a feature that cannot be replicated quickly. It requires regulated, independent key-holding partners, legal agreements, quorum governance frameworks, and operational trust-building. Onramp has operated MIC since 2023, and no other Bitcoin financial platform currently offers it at the consumer level. The practical effect is that Onramp clients have a clear path from a free qualified-custodian arrangement to institutional-grade distributed custody, on a single platform, without rebuilding their financial relationships when they upgrade. Cash App users do not have an equivalent path within the product.

Fees and the Comprehensive Platform Argument

Cash App can beat Onramp's free Finance tier on per-trade brokerage at the headline. But that is not the question Onramp is built to answer. Onramp is a comprehensive platform built for financial services that grow your Bitcoin wealth over time. Cash App is built to make buying Bitcoin easy inside a consumer banking app. Those are different products solving different problems.

Brokerage fees. Cash App's fee structure has two very different halves. On recurring buys (Auto Invest), Round-Ups, direct deposit, and one-time purchases over $2,000, Cash App charges zero fees and zero spread, which is genuinely hard to beat. On one-time purchases under $2,000, though, Cash App charges a tiered service fee that grows the smaller the purchase, historically on the order of 1.5% to 3% on smaller buys and easing toward 0.75% to 1% near the $2,000 threshold, plus a 0% to 0.75% spread. Onramp charges a flat 0.85% at the free Finance tier (0.65% at Core, 0.32% at Private) on one-time buys, and recurring buys are zero-fee. The practical result is that the two platforms tie on recurring dollar-cost-averaging (both free), Cash App wins on large one-time purchases over $2,000, and Onramp is typically the cheaper option for the everyday buyer making smaller one-time purchases, where Cash App's percentage fee climbs well above Onramp's flat 0.85%.

The earn account and the Onramp Card. Onramp adds two accumulation surfaces Cash App does not match in the same form. The earn account pays up to 3% at Finance (Onramp-funded rewards from corporate revenue, not interest paid on a deposit), scaling to 4% at Core and 5% at Private. Cash App Savings pays up to 3.25% but requires a Cash App Card plus $300/month direct deposit, and it is a dollar savings rate rather than a Bitcoin-accumulation surface. The Onramp Card pays 0.5% cash-back at Finance, paid in dollars and convertible to Bitcoin in one click, scaling to 1% at Core and 1.5% at Private. Cash App does not currently offer a comparable Bitcoin cash-back card.

The fuller picture. Onramp is built to grow a Bitcoin position across multiple surfaces, including brokerage, earn, the Onramp Card, Arch loans, an optional IRA, the Onramp Terminal research, and Multi-Institution Custody at Core. Cash App does not have most of those surfaces. The two platforms are not competing on the same surface area, which is why a per-trade brokerage comparison only captures part of the picture.

Financial Services: IRA, Loans, Inheritance, Research

This is where Onramp and Cash App diverge most dramatically.

Bitcoin IRA. Cash App does not offer a Bitcoin IRA. Holders who want tax-advantaged Bitcoin exposure have to use a separate provider, which adds counterparty relationships and account-management complexity. Onramp offers Bitcoin IRAs in Traditional, Roth, SEP, and Solo 401(k) structures: as a $100/month add-on at the free Finance tier (custodied at BitGo Trust), or included in the monthly fee at Onramp Core (custodied using Multi-Institution Custody). Onramp Core is the only platform combining a tax-advantaged Bitcoin retirement account with Multi-Institution Custody architecture.

Bitcoin-backed loans. Cash App does not offer them. Onramp offers Bitcoin-backed loans through Arch Lending in a centralized structure with no rehypothecation, no wrapped Bitcoin, and no DeFi protocol exposure, with up to 50% loan-to-value, fixed rates for the loan term, and an optional deferred interest payment structure where interest is paid at the end of the loan rather than monthly. Arch is the lender and holds the Bitcoin collateral with Anchorage, a regulated qualified custodian, for the life of the loan; it is not lent out or otherwise put to work to fund the loan. For holders who want to borrow against Bitcoin without selling it, this is a service Cash App does not provide.

Inheritance planning. Cash App does not offer integrated inheritance planning. Bitcoin held on Cash App passes through the account holder's estate, but the operational handling is not built into the product. Onramp Core includes integrated inheritance planning where you designate a beneficiary at account setup and the heir presents a death certificate at the time of transfer, with the Multi-Institution Custody architecture operating in the background and no hardware wallets or seed phrases for the heir to learn. For families where the primary beneficiary is a non-technical spouse or adult child, the institutional handoff is one of the largest practical reasons holders upgrade to Onramp Core.

Research and data. Cash App provides basic price information. Onramp includes the Onramp Terminal at no additional cost, at every tier including free Finance: a Bitcoin-only research and data platform with thousands of interactive charts covering on-chain metrics, macro overlays, miner economics, ETF flows, and derivatives positioning. The same consolidation thesis that drives the rest of Onramp applies to research: rather than stitching together separate data subscriptions, the Terminal puts everything inside the platform where the cash, brokerage, custody, and loans also live.

Customer Service and Security History

Cash App serves tens of millions of users. Customer service is delivered primarily through in-app support, chatbots, and email tickets. For straightforward account questions, the model works at scale. For non-standard situations or larger Bitcoin balances, the support model is less suited. On the structural side, the single-custodian arrangement and the fact that Bitcoin on Cash App is explicitly uninsured (per the company's own disclosures) are relevant data points for holders evaluating where to keep a significant Bitcoin position. None of this is a unique critique of Cash App; every consumer app at that scale faces similar pressures. But it is worth weighing.

Onramp provides direct human client service through Onramp Client Services. Every client can speak with a real person who knows the platform. The Multi-Institution Custody architecture at Onramp Core is also designed to make account-level security incidents structurally less catastrophic, because no single compromised credential or interface can move client Bitcoin unilaterally.

When to Choose Each

Cash App is the right answer for holders whose Bitcoin activity is consumer-scale and integrated with day-to-day banking. If you are dollar-cost-averaging using direct deposit or Round-Ups, using Lightning to send small payments, and managing your everyday money through Cash App, the product is built for that flow, and its zero-fee buy tiers are hard to beat on price. The withdrawal limits ($10K/day, $25K/week) are reasonable for consumer use but are a real friction for holders building serious positions.

Onramp is the right answer for holders whose focus is Bitcoin specifically and who want a platform built to grow their Bitcoin wealth. You enter through the free Finance tier, which matches Cash App on buying and holding while consolidating brokerage at 0.85%, an earn account, the Onramp Card with cash-back convertible to Bitcoin, Bitcoin-backed loans through Arch Lending, an optional Bitcoin IRA, the Onramp Terminal research platform, and qualified-custodian custody on a single platform. As the position grows, the platform scales to Multi-Institution Custody, an included IRA, and integrated inheritance at Onramp Core, and to dedicated management and a Virtual Family Office at Onramp Private. Onramp built its custody foundation first and has operated Multi-Institution Custody continuously since 2023. Most Bitcoin holders today are running their financial lives across an exchange, a separate custody solution, a separate IRA custodian, a separate lender, and a bank for cash. The fragmentation introduces counterparty risk, operational complexity, and inheritance gaps. Onramp is built to close that gap.

For many holders, the two products are not strictly mutually exclusive. Using Cash App for everyday Bitcoin payments and Lightning transactions while holding and growing the bulk of a serious Bitcoin position at Onramp (upgrading from Finance into Core as the position warrants) is a reasonable pattern. Each platform serves a part of the Bitcoin life the other does not.
