Bottom line
Kolo Card rewards newcomers generously but drops to 1% after month one, capped at $100 monthly. No physical card yet. Best for crypto spenders who want Bitcoin cashback without monthly fees.
Kolo Card's 5% first-month cashback is a strong opening offer, but the permanent drop to 1% afterward is a significant step down. The $100 monthly cap limits value for heavy spenders. Virtual-only format and custodial setup are real constraints worth weighing.
The Kolo Card is issued by Rain out of Puerto Rico and runs on the Visa network. It is a custodial debit card available only as a physical card. The card supports Apple Pay. Funding works through auto-conversion from any of 15 supported cryptocurrencies across 7 blockchains, including BTC, ETH, SOL, USDC, and others. Conversion costs 0.32% per transaction, and a 1% FX fee applies to non-USD purchases. The card is denominated in USD and covers 172 countries. KYC is required to sign up. No personal bank account or IBAN is provided. Opening a card requires a 10 USDC deposit, which is fully spendable. Daily spend limit is $50,000. ATM withdrawals are not available.
Kolo Card pays Bitcoin cashback on all purchases. During your first month, every transaction earns 5% back in BTC, with a $5 cap per purchase and a $100 monthly cap. After that first month, the rate falls permanently to 1%, with a $1 cap per purchase and the same $100 monthly ceiling. A typical user spending $500 a month after the introductory period earns $5 in BTC cashback. The Bitcoin reward may appreciate over time if BTC rises, but that carries market risk. There are no tiers, staking requirements, or paid plans to unlock higher rates.
