Onramp IRA vs Choice (Kingdom Trust): Integrated vs Self-Directed Custody

Onramp IRA and Choice by Kingdom Trust represent two different product configurations for holding Bitcoin in a tax-advantaged retirement account. Onramp is an integrated Bitcoin IRA where the platform combines administration with multi-institution custody under a single relationship. Choice is a self-directed IRA platform supporting Bitcoin alongside other alternative assets, with the holder selecting the underlying custody arrangement from multiple options. The comparison is less about ranking two competing products than about identifying which configuration fits which holder profile.

Key Takeaways

• Onramp is an integrated Bitcoin IRA with multi-institution custody bundled into a single provider relationship
• Choice is a self-directed IRA platform where the holder selects the underlying custody arrangement, with Bitcoin alongside other alternative assets supported in the same IRA
• Choice offers flexibility over the custody configuration; Onramp offers operational simplicity through a pre-defined custody architecture
• Fee structures price different scopes of work; Choice charges a flat administrative fee plus per-trade fees and any custodian-specific fees, while Onramp charges a basis-point annual fee with no trading commissions
• Choice supports a broader asset universe inside the same IRA; Onramp is Bitcoin-only
• Holders with multi-asset alternative allocations or specific custody configuration requirements typically fit Choice; holders with Bitcoin-only intent and integrated-platform preferences typically fit Onramp

Two Different Product Configurations

Choice by Kingdom Trust: Self-Directed Platform

Kingdom Trust is an IRA custodian for alternative assets with over a decade of operational history; the Choice platform offering Bitcoin support is a newer extension of that infrastructure. The defining characteristic of the model is architectural flexibility: holders can select the Bitcoin custody configuration that fits their preferences rather than accepting a pre-defined arrangement.

The platform supports Bitcoin alongside other alternative assets including real estate, private equity, precious metals, and private notes within the same IRA structure. For holders whose retirement allocation includes Bitcoin alongside non-Bitcoin alternatives, the consolidation under a single self-directed IRA reduces administrative overhead relative to maintaining multiple separate accounts.

Onramp IRA: Integrated Bitcoin IRA

Onramp operates an integrated Bitcoin IRA where the platform combines administration with multi-institution custody. The custody architecture is pre-defined (2-of-3 multisig across three independent regulated custodians) and the platform is Bitcoin-only by design.

The defining characteristic is operational simplicity through integration. Holders interact with one provider for all account functions, with the custody architecture, trading workflow, and inheritance administration all coordinated through the single relationship.

Side-by-Side Comparison

Custody Architecture

• Choice: Multiple custody configurations including partner qualified custodian arrangements, collaborative custody options, and self-custody-compatible structures. The holder selects the configuration
• Onramp: 2-of-3 multi-institution multisig with three independent regulated custodians. Pre-defined architecture, no holder selection

Fee Structure

• Choice: Setup fees plus annual administrative fees of approximately $0 to $195 per year, plus 1% per-trade fees plus any custodian-specific fees that apply to the selected configuration
• Onramp: 0.25% annual custody fee with 0% commission on trades inside the IRA. No setup fees

The all-in cost depends substantially on the configuration. Holders modeling specific configurations should obtain detailed fee schedules from both providers.

Asset Coverage

• Choice: Bitcoin plus real estate, private equity, precious metals, private notes, tax liens, and other alternative assets within the same IRA
• Onramp: Bitcoin only

For holders with multi-asset alternative allocations, Choice's breadth is structural; Bitcoin-only providers cannot replicate it.

Account Types Supported

• Choice: Traditional, Roth, SEP, SIMPLE, and Solo 401(k)
• Onramp: Traditional, Roth, SEP, SIMPLE, and Solo 401(k)

Functionally equivalent.

Operational Complexity

• Choice: Higher complexity. The holder coordinates between the IRA administrator and one or more custodians, ensures asset documentation, and maintains records establishing IRA ownership of each asset
• Onramp: Lower complexity. Single integrated provider relationship; no separate custodian coordination

Prohibited Transaction Risk

• Choice: Self-directed IRAs are subject to IRS prohibited transaction rules that can disqualify the entire IRA if violated. Multi-asset structures with real estate or private business holdings introduce more opportunities for inadvertent violations
• Onramp: Bitcoin custody arrangements are difficult to use in prohibited ways; the risk is materially lower

Inheritance

• Choice: Standard IRA beneficiary designation; the inheritance workflow depends on the specific asset configuration in the IRA at the time of death
• Onramp: Transfer on Death beneficiary designation with bundled inheritance administration and deep trust-titling support

Where Choice Wins

• Multi-asset breadth in a single IRA — Bitcoin alongside real estate, private equity, and other alternatives
• Configuration flexibility for holders with specific custody preferences not available through integrated providers
• Pre-existing self-directed IRA relationships that can be extended to Bitcoin without opening a separate account
• Established Kingdom Trust history as an alternative asset IRA custodian

Where Onramp Wins

• Operational simplicity with one provider, one custody arrangement, one bundled fee structure
• Multi-institution custody architecture as the default rather than as one option among many
• Lower prohibited transaction risk through Bitcoin-only Single-purpose structure
• Zero trading commissions inside the IRA
• Bundled inheritance and trust-titling

Decision Framework

Holders for Whom Choice Is the Stronger Fit

• Holders with retirement allocations including Bitcoin and other alternative assets
• Holders who already operate a self-directed IRA for other assets and want to extend to Bitcoin
• Holders requiring specific custody configurations that integrated Bitcoin IRA providers do not offer
• Holders comfortable with the operational complexity and prohibited transaction risk of self-directed structures

Holders for Whom Onramp Is the Stronger Fit

• Holders whose retirement allocation in this IRA is Bitcoin-only
• Holders who want operational simplicity through a single integrated relationship
• Holders who consider single-custodian concentration risk a primary concern (Onramp's pre-defined multi-institution architecture addresses this)
• Family offices, RIAs, and trust beneficiaries requiring institutional documentation

Evaluating This Comparison with Proof of Custody

The choice between an integrated Bitcoin IRA and a self-directed IRA platform with Bitcoin support is one of the first decisions a holder makes when establishing Bitcoin exposure in a retirement account. The right choice depends on intended asset allocation, operational preferences, and tolerance for the complexity of self-directed structures. For holders evaluating either configuration, the Proof of Custody methodology applies consistently across both: Bitcoin IRA Scoring Methodology.
