What a $100 BTC buy actually costs by country and payment method: 10-country data

Short reference for anyone making their first BTC buy. Costs vary a lot by country and even more by the payment method you choose.

Card rail country medians on a $100 BTC buy:

Canada 4.90%

Singapore 2.30%

Australia 2.10%

United States 2.10%

Germany 1.50%

France 1.50%

United Kingdom 1.50%

Netherlands 1.50%

Sweden 1.50%

Poland 1.40%

Bank rail (ACH in US, SEPA in EU, Interac in CA, Faster Payments in UK) sits at roughly 0.2 to 0.3 percent in every country tracked.

The practical takeaway for a first-time buyer: use bank transfer instead of credit or debit card if you can tolerate the extra day of settlement time. The cost difference is roughly 5 to 20 times, not a few percent.

Caveat: these are country medians across tracked exchanges, not a quote for a specific transaction. Your specific exchange, card BIN, and promo state will move the number.
