Rates shown are for NEXO Token payouts; choosing BTC pays 0.1% to 0.5%. Monthly reward caps reset on the 1st.
Availability and KYC
KOSH does not publish a country list. KOSH says it supports onboarding in 90+ countries without publishing the list.
Nexo is offered in 33 countries, including France, Germany, Ireland, Italy, Netherlands, Portugal, Spain, United Kingdom and Argentina. Nexo lists the EEA, Andorra, Monaco, the UK and Argentina "and other selected jurisdictions", so the list is not complete; the app's Check eligibility screen is final. Bulgaria is excluded because Nexo says its services are unavailable there. Personal accounts only. The card can be issued in EUR, GBP or USD. The DiPocket card terms cover EEA and UK residents only; the issuer for Argentina is not published.
KOSH needs full KYC and Nexo needs full KYC.
The card finder checks both cards against your country, KYC level and must-have features.

KOSH publishes ATM withdrawals of up to $750 a day.
Nexo publishes a daily spending limit of €70,000, a monthly limit of €300,000 and ATM withdrawals of up to €2,000 a day.
KOSH works with Apple Pay and Google Pay, and Nexo works with Apple Pay and Google Pay. Nexo issues a virtual card you can use straight away.
Custody and safety
KOSH scores 44/100. Licensing: we could not confirm a licence for the card issuer on its own website. No incidents or enforcement actions found in the last 36 months. KOSH (Piers Technology Inc.) says it is a financial technology company, not a bank or a money services business, and that some services are provided by licensed partners it does not name. It says stablecoin holdings sit with regulated custodians.
Nexo scores 63/100. Licensing: issued by a bank or e-money institution regulated in a tier-one jurisdiction. The card is issued through DiPocket UAB. 2023-01-19: Nexo Capital Inc. agreed to pay a $22.5 million SEC penalty, plus $22.5 million to US state regulators, over its unregistered Earn Interest Product. 2026-01-14: California's DFPI fined Nexo Capital Inc. $500,000 for making loans to California residents without a lender licence and without checking their ability to repay. Card funds are not stored with DiPocket; Nexo settles each card transaction, and the card terms say DiPocket "does not issue electronic money to you". Nexo's real-time reserves attestation (Armanino from 2021, Moore Johannesburg from April 2023) no longer has a live page, and we found no dated reserves report for 2025 or 2026.
