BLOX versus Kraken
Choosing between BLOX and Kraken comes down to more than the brand name. What matters is how much of your money arrives once every fee and the exchange rate are counted. This page puts a number on that.
In our comparison, BLOX belongs to the crypto exchange category and handles Currencies, Cryptocurrencies, while Kraken belongs to crypto exchange with support for Currencies, Cryptocurrencies. This already says a fair bit about when one can stand in for the other.
Further down this page you can read how we work out the cost, where each provider tends to do well and which one fits which situation. Because the rates are live, the outcome can shift during the day.
Who should pick BLOX and who Kraken?
For travel spending, compare what a card payment in a foreign currency costs at each. Whichever of the two offers a usable card for your destination has a head start.
If you send money abroad regularly, the total cost per transfer and the delivery time are what count. For large amounts, such as a house deposit or tuition, even a small margin difference adds up, and limits and verification matter as well.
For buying digital assets, check that crypto is supported at all, then compare spreads and withdrawal fees. For business payments, check whether a business account is available and what it costs. Nothing here is investment advice.
How we calculate the cost
There are two parts to the price of any conversion: the fee you see and the markup on the rate that you often do not. As a benchmark we use the live mid-market rate, the rate banks and large traders use among themselves. The gap is the margin, and we add it to the fee.
We test a range of sample amounts, small, medium and large, because fixed fees and percentage fees behave differently. Rates refresh every 30 minutes and fees come from the providers’ published fee schedules. Promotions, account tiers and personal discounts are not always included, so your own offer may differ.
This comparison is independent. Affiliate links help pay for the site, but the ranking is based on cost alone. The numbers decide, not the commission.
Same category, different details
BLOX and Kraken are both in our crypto exchange category, so this is a like-for-like comparison. That makes the differences smaller, but they still matter.
Start with coverage: supported currencies, countries and payment methods. BLOX covers Currencies, Cryptocurrencies, Kraken covers Currencies, Cryptocurrencies. If one of them does not cover your currency, the choice is made for you.
Then compare price on the route you actually use, along with practical matters such as the app and customer service. Because they are so similar, trying the other one later costs little.
Switching between BLOX and Kraken
Many people do not use one provider for everything. It is perfectly normal to keep BLOX for one task and Kraken for another. Expect to verify your identity with each provider separately.
Each time you plan a bigger conversion, run the amount through the calculator, because the cheapest option can change with the rate and the amount. It is a quick check that pays off.
If you switch, withdraw or spend your remaining balance first and save your statements, as you may need them later for your tax return.
Where the real cost hides
“No fees” is one of the most common claims in money transfer, and one of the most misleading. Often the cost simply moves into the exchange rate, where it is harder to spot. A margin of a fraction of a percent sounds small, but it grows with every amount you convert.
That is why we always look at the total: fee plus margin. BLOX and Kraken may structure their pricing differently, one with a visible fee and a tight rate, the other with no fee and a wider spread. What counts is what lands in the account at the end.
Also look beyond the conversion: card payment fees, surcharges for weekends or rare currencies, and costs on the receiving side. We include what is published, but it pays to double-check before a large transaction.
Speed: BLOX vs Kraken
BLOX lists its quickest option as Instant, while Kraken lists Instant. These are best cases, not guarantees. A first transfer often takes longer because of identity checks.
Speed often depends on how you pay. Paying by card tends to be faster, and sometimes more expensive, than a standard bank transfer. When there is no rush, a slower option can save you money.
Convenience counts too: clear status updates and an app you like save time and stress. A small test transfer tells you more than any review.
Which one is cheaper?
In 3 of 3 scenarios we can test on both sides, Kraken delivered the better result once fees and exchange rate were counted. On price alone, that makes Kraken the default pick.
This does not rule out BLOX. Check the table above to see the routes where BLOX does better, and if your own transfer matches one of those rows, that single row counts more than the total score.
Price is also not the only factor. BLOX may support a payment method, a currency or a delivery option you need. For small sums, those practical points can outweigh the price difference.
Regulation and safety
Cheap is only good if your money is in safe hands. A legitimate provider is licensed or registered with a financial regulator. Providers normally list their licence and the supervising authority on their website.
For money services, the key word is safeguarding: your balance should be held apart from the firm’s own money. That is a different kind of protection from a bank deposit guarantee scheme.
Crypto exchanges deserve extra scrutiny: ask about registration, custody and withdrawal options. Whichever you choose, switch on two-factor authentication and use a unique password.
What to compare between two exchanges
With two crypto exchanges, the cost is spread over several layers. First the spread: the difference between buy and sell price on a simple purchase. If you use the order book, maker and taker fees replace the spread as the main cost.
Then there are deposit and withdrawal costs. How you fund your account, by bank transfer, card or another method, changes the cost. Withdrawing coins to your own wallet comes with a network or withdrawal fee that varies per asset.
Custody is the last point. Coins on an exchange are held by that exchange, not by you. Many users move larger holdings to a wallet they control, which makes the withdrawal fee part of the real cost.
Small amounts vs large amounts
The size of the amount can change the winner. Fixed fees hit small transfers hardest; percentage margins hit large ones hardest. Our scenario table reflects this by testing several amounts.
If you move larger sums regularly, check whether tiered pricing applies, and your own price may then be better than the one shown. For any large transfer, confirm the final quote in the app before you approve it.
