Which Bitcoin IRA Should I Choose? Provider Comparison

Bitcoin IRA Providers Compared

A Bitcoin IRA is a self-directed retirement account that allows you to hold Bitcoin and other digital assets inside a tax-advantaged structure. Unlike a standard Bitcoin ETF held in a brokerage IRA, a crypto IRA gives you exposure to the underlying asset, with custody models ranging from fully managed to multisig self-custody.

The tradeoff is complexity: providers differ widely in fees, supported account types, custody arrangements, and the number of assets available. The following table compares six active providers across the dimensions that matter most.

Choice by Kingdom Trust previously appeared in most comparisons. Kingdom Trust merged into Digital Trust in January 2024, and the Choice platform now operates under Digital Trust custody. Alto's CryptoIRA business was acquired by Public (the investing app) in November 2025 for $65 million, with account migration ongoing through 2026. Alto is listed above because the product remains active under its existing fee structure.

Fee Structures Explained

Bitcoin IRA fees break down into three categories: trading fees charged per transaction, recurring custody or platform fees, and one-time setup costs. Over a long holding period, recurring fees compound significantly and often outweigh trading costs.

The 5-year cost column assumes a single $50,000 buy-and-hold position with no additional trades. If you dollar-cost average monthly, trading fees multiply accordingly. Providers with zero annual fees (iTrustCapital, Alto) become more expensive for active traders, while flat-fee providers like Unchained favor larger, less frequent positions.

Account Types and Contribution Limits

The IRS treats cryptocurrency as property, not currency. This means Bitcoin held inside a retirement account follows the same contribution limits and distribution rules as any other IRA asset. For 2026, the limits are:

• Traditional and Roth IRA: $7,500 per year ($8,600 if age 50 or older)
• SEP IRA: up to 25% of net self-employment income, capped at $72,000
• Solo 401(k): $24,500 employee deferral plus up to 25% employer contribution, capped at $72,000 total ($80,000 if age 50+)

The account type you need determines which providers are available. iTrustCapital, BitcoinIRA, Alto, and Unchained all support SEP IRAs, making them suitable for self-employed individuals who want higher contribution limits. For Solo 401(k) plans, IRA Financial is the standout option, allowing combined contributions up to $72,000.

Note: Starting in 2026, the SECURE Act 2.0 requires participants earning over $150,000 in W-2 wages to designate catch-up contributions as Roth. This applies to Solo 401(k) plans and may affect your tax planning.

Custody and Security Models

Custody is the single most important differentiator between Bitcoin IRA providers. It determines who controls your private keys and what happens to your Bitcoin if the provider shuts down.

Institutional Custody

Most providers use third-party institutional custodians. iTrustCapital uses Fortis Bank as the qualified custodian, with Coinbase Custody, Fidelity Digital Assets, and Fireblocks providing the cold storage infrastructure. BitcoinIRA stores assets with BitGo in 100% offline cold storage using multi-signature wallets, backed by up to $250 million in custody insurance through Lloyd's of London. Alto routes through Coinbase Custody. In all three cases, the provider holds the keys on your behalf: you cannot withdraw Bitcoin to your own wallet.

Self-Custody via Multisig

Unchained IRA is the only provider offering true self-custody within a retirement account. Their 2-of-3 multisig model gives you two of the three keys, stored on hardware signing devices. Unchained holds the third key for recovery purposes. The IRA custodian (Fortis Bank) holds legal title as required by the IRS but delegates actual key control to you and Unchained. Because you hold the quorum (two keys), you can move your Bitcoin even if Unchained ceases operations. The tradeoff is a higher annual fee ($250) and Bitcoin-only support.

Self-Directed Exchange Access

IRA Financial takes a different approach: they establish the self-directed IRA or Solo 401(k) structure, but you trade directly on supported exchanges. This gives you more control over execution but introduces operational complexity and requires careful record-keeping.

Choosing by Investor Profile

The right provider depends less on which platform has the lowest fees and more on how you plan to use the account. Three common profiles illustrate the tradeoffs.

Early Accumulator (Under 40, DCA Strategy)

If you are making regular contributions and dollar-cost averaging into Bitcoin over decades, trading fees compound with every purchase. Alto CryptoIRA's $10 minimum and 1% fee with no annual charge make it practical for small, frequent buys. iTrustCapital is similarly cost-effective with a slightly higher $1,000 entry point but adds access to physical precious metals for portfolio diversification.

Pre-Retiree (50+, Lump Sum or Rollover)

Investors rolling over a 401(k) or traditional IRA into a Bitcoin position typically make one or two large trades and then hold. For this profile, recurring fees matter more than trading costs. Swan Bitcoin's 0.02% monthly fee stays low on moderate balances, while Unchained's flat $250 annual fee becomes cost-efficient above roughly $100,000 in holdings. Pre-retirees should also weigh Unchained's multisig custody model against the convenience of managed custody, especially when planning Bitcoin inheritance.

Self-Employed (SEP IRA or Solo 401k)

Self-employed investors can contribute up to $72,000 per year through a SEP IRA or Solo 401(k). iTrustCapital, Alto, and Unchained support SEP IRAs. For Solo 401(k) plans with Roth sub-accounts, IRA Financial provides the structure at $100 per year (or $495 flat for the plan setup). The Solo 401(k) also allows loans against your balance, which SEP IRAs do not permit.

Roth Conversion Strategies for Crypto

A Roth conversion moves assets from a pre-tax account (Traditional IRA, 401(k)) into a Roth IRA. You pay income tax on the converted amount today, but all future growth and qualified withdrawals are tax-free. Bitcoin's volatility makes this strategy particularly interesting.

Converting during a market downturn reduces the taxable amount. If you convert $30,000 worth of Bitcoin that later appreciates to $150,000, the $120,000 gain is never taxed. Many investors time conversions during bear markets or immediately after halving cycles when prices may be depressed relative to long-term expectations.

Two rules constrain the strategy: the five-year holding period (each conversion has its own clock), and the age 59½ requirement for penalty-free withdrawals. The optimal window for conversions is often between early retirement and the start of Required Minimum Distributions (age 73 for those born 1951 to 1959, age 75 for those born 1960 or later), when taxable income is lowest and bracket space is available.

What to Watch Out For

Several risks apply to all Bitcoin IRA providers regardless of their fee structure or custody model.

• Prohibited transactions: the IRS prohibits self-dealing inside IRAs. You cannot use IRA-held Bitcoin as collateral, lend it for yield, or transfer it to a personal wallet. Violations can disqualify the entire account and trigger immediate taxation.
• Illiquidity at exit: most providers require you to sell Bitcoin to fiat inside the account before taking a distribution. Only Unchained allows in-kind Bitcoin distributions (transferring actual BTC out of the IRA).
• No FDIC or SIPC protection: crypto IRAs are not covered by federal deposit insurance or securities investor protections. Some providers carry private insurance through their custodians, but coverage limits vary. Uninvested USD balances may be FDIC-insured separately.
• Platform risk: if a provider ceases operations, your assets are held by the qualified custodian (not the provider), but migration can be slow and disruptive. Self-custody models like Unchained mitigate this by ensuring you always hold a quorum of keys.

Frequently Asked Questions

Can I hold Bitcoin in a Roth IRA?

Yes. The IRS classifies Bitcoin as property, and there is no prohibition on holding property inside a Roth IRA. You need a self-directed IRA custodian that supports digital assets. All six providers listed above offer Roth IRA accounts. Contributions are made with after-tax dollars, and qualified withdrawals (after age 59½ with the account open for at least five years) are completely tax-free, including any Bitcoin appreciation.

What is the cheapest Bitcoin IRA?

For buy-and-hold investors, Alto CryptoIRA and iTrustCapital are the lowest-cost options: both charge a 1% trading fee with no annual or monthly charges. For larger balances above $100,000, IRA Financial's flat $100 annual fee and 1% trading fee result in lower total costs than AUM-based fee models. The cheapest option depends on your balance size, trading frequency, and whether you need features like self-custody.

Is a Bitcoin IRA better than a Bitcoin ETF in a regular IRA?

A Bitcoin ETF (such as those holding spot BTC) inside a standard brokerage IRA charges expense ratios between 0.15% and 0.25% annually with no trading commissions at most brokers. This is significantly cheaper than any crypto IRA provider. However, ETFs give you exposure to Bitcoin's price, not the asset itself: you cannot withdraw actual Bitcoin, use multisig custody, or hold altcoins. For a deeper comparison, see our Bitcoin ETF vs direct purchase tool.

Can I transfer Bitcoin I already own into an IRA?

No. The IRS does not allow in-kind contributions of cryptocurrency to an IRA. You must contribute cash (USD) to the IRA, then purchase Bitcoin within the account. Transferring existing Bitcoin into an IRA would be treated as a taxable sale followed by a cash contribution. The only exception is a rollover from another retirement account that already holds crypto.

What happens to my Bitcoin IRA if the provider goes out of business?

Your assets are held by a regulated qualified custodian (such as Fortis Bank or Digital Trust), not by the platform itself. If the provider shuts down, the custodian retains your holdings and you can transfer to another provider. With Unchained's multisig model, you hold two of the three keys directly, so you retain access regardless of the provider's status.

Do I pay taxes on Bitcoin gains inside an IRA?

No, gains inside an IRA are not taxed when they occur. In a Traditional IRA, you pay ordinary income tax on withdrawals in retirement. In a Roth IRA, qualified withdrawals are entirely tax-free. This eliminates the need to track individual cost basis for each trade inside the account, which simplifies crypto tax reporting considerably.

Can I use a Solo 401(k) for Bitcoin?

Yes. A Solo 401(k) is available to self-employed individuals with no full-time employees (other than a spouse). It allows combined contributions up to $72,000 in 2026 ($80,000 if age 50 or older), significantly more than a standard IRA. IRA Financial supports Solo 401(k) plans with crypto access. Unlike SEP IRAs, Solo 401(k) plans also allow Roth contributions and participant loans.
