This is a criteria-based shortlist, not a ranking by commission. Below is exactly how we decided, the six criteria that matter for a first purchase, and — critically — what you should verify yourself before choosing, because fee schedules and eligibility change.
The six criteria that matter for a first purchase
- Fees, all of them. Not just the advertised trading fee. A first purchase usually involves a deposit (bank transfer), a trade (fee or spread), and later a withdrawal (network fee, sometimes a flat fee). The total cost of a $100 first purchase can differ meaningfully between platforms. See crypto fees explained for what each fee type is.
- Eligibility where you live. Features, assets, and even basic account access vary by country and state. Verify in your jurisdiction before investing time in setup.
- Onboarding friction. Identity verification (KYC) is required at regulated US exchanges. The question is how smoothly it works: what documents, how long, whether your bank transfer method is supported.
- Security track record. Look for: history of incidents and how they were handled, whether customer funds are separated, and what (if anything) is covered if the platform fails. No exchange is "safe" in the way a deposit-insured bank account is — exchange protections are not deposit insurance.
- Withdrawal paths. Can you move coins to your own wallet (self-custody) without friction or unusual restrictions? A platform that makes withdrawal hard is a red flag worth understanding.
- Support and clarity. When something goes wrong, is there a real, documented support path? Vague terms and unreachable support are how small problems become lost money.
The shortlist
| Criterion | Coinbase | Kraken |
|---|---|---|
| Fee structure | Check the current schedule on the official Coinbase fees page — our research environment can't retrieve it automatically, so we won't quote numbers we haven't verified. | Transparent, volume-tiered maker/taker fees. Base tier (from $0 30-day volume): 0.40% maker / 0.80% taker, decreasing as volume rises (official fee schedule, checked October 1, 2026). Separate tables apply to the Kraken app and Kraken Pro — check which product you'll use. |
| Eligibility | Verify current availability for your state/country on the official site before signing up. | Verify current availability for your state/country on the official site before signing up. |
| First-purchase fit (editorial) | Strong fit for users who prioritize the simplest onboarding and smallest first step. | Strong fit for users who expect to make more than one purchase and want to see exactly what fees apply at each volume tier. |
| Custody risk | While coins sit on either platform, the platform holds them. For amounts you plan to keep, moving them to your own wallet is the durable protection — see wallets explained. | |
How to read the "editorial" row: those are our judgments under the published criteria above — useful, but not facts you can verify on a fee page. The fee and eligibility rows are the ones to check yourself, today, before you decide.
Which one fits you?
- Make one small first purchase, then decide. If your goal is simply to learn what owning and using crypto feels like, the lower-friction option usually wins. Keep the amount small enough that a 50% drop would be an education, not a hardship.
- Plan to keep buying or trading. If you expect recurring purchases, the fee structure matters more. Work the numbers with our fee calculator using each platform's current rates before choosing.
- Plan to hold long-term. The exchange you buy on matters less than where you store. Budget time (and a small hardware-wallet cost) for moving coins to self-custody — we walk through the transfer.
Methodology
We shortlisted the two exchanges most commonly relevant to a first US purchase, then evaluated each against the six criteria above. Factual details (fees, product structure) come from official pages and are dated in Sources; editorial judgments are labeled as such. We re-verify commercial details monthly, and we never order rankings by commission size. Full method: review methodology. If you use a different country, several rows above will not apply to you — check the official sites for your region.
