Why this matters
Payment rail choice is a first-order retail cost lever.
The median same-exchange premium of 12.00x means rail selection can dominate exchange selection for many buyers.
In dollar terms, the largest same-exchange example is $52.94 extra on a $1,000.00 buy at Kraken.
For recurring buyers at $1,000.00/month, the median gap compounds to roughly $336.60 per year.
Claim boundary
This is not one outlier: in same-exchange BTC comparisons in the US, card costs more than bank on 20 of 21 exchanges that offer both payment methods, and the cheapest bank-transfer option beats the cheapest card option in 13 of 13 tracked countries.

What this proves
- Same-exchange comparisons use card and bank on the same exchange for BTC in the US.
- Country comparisons use each country's cheapest card vs cheapest bank option.
- Median and ratios are reproducible from the published paired-exchange rows.
What this does not prove
- Bank transfer is not always operationally easier or faster.
- This does not rank exchanges by quality, reliability, or trustworthiness.
- Withdrawal fees, network fees, and FX conversion costs are not included.
