Kast: $10 FX fee (2%), earn $30 back (6%). Net: +$20
RedotPay: $11 FX fee (~2.2%), zero rewards. Net: -$11
Kast still wins, even with higher FX fees, because rewards more than compensate.
Scenario 3: $50/month on small purchases, non-USD
Kast: Small transaction surcharges + 2% FX = ~$1.50–$2 in fees, earn $3 back. Break-even territory.
RedotPay: ~$1.10 FX (2.2%), no rewards. Net: -$1.10
This is where it gets close. For very small, non-USD spending patterns, the difference is minimal.
At almost any spending level above $200/month, Kast’s Season 5 rewards make it the better deal even with the higher FX fee. a specific, well-defined regulatory framework. Kast is US-based with a Visa partnership through Third National Bank, which is solid but a different regulatory environment.
Simplicity. No seasons, no token mechanics, no TGE speculation. RedotPay is simple: load coins, spend, pay the FX fee. For users who find the $MOVE/$KAST reward system too complex, RedotPay is the cleaner product.
What Kast does better
US virtual bank account. This is a meaningful differentiator. Kast gives you a US routing number (ACH + Fedwire) you can use to receive USD from platforms like Upwork, Fidelity, or Interactive Brokers. RedotPay offers nothing comparable. For freelancers and investors with US-denominated income, this is a significant advantage.
Rewards. 6% on the free Standard tier during Season 5 is the best cashback rate in the crypto card space right now. RedotPay offers zero.
Multiple virtual cards. Kast includes 2 free virtual cards and allows more at $2 each. Useful for separating subscriptions, testing merchant compatibility, or privacy purposes.
If you’re a freelancer getting paid in USD via Upwork or similar platforms, Kast’s US bank account feature alone justifies using it over RedotPay — the ACH routing number effectively replaces Payoneer or Wise for receiving USD, at a fraction of the cost.
Should you use both?
Many users run both cards simultaneously, which is a reasonable approach:
Kast for large USD purchases, online subscriptions (Netflix, Amazon, Adobe), and platforms where you want maximum rewards
RedotPay for everyday local spending in non-USD currencies where the small-transaction surcharge makes Kast less efficient
Both cards are free to maintain. There’s no penalty for holding both.
The one caveat: Kast’s Season 5 ends March 31, 2026
The 6% rewards rate is Season 5-specific. When Season 6 launches, the terms may change. RedotPay’s fee structure, by contrast, has been consistent.
If you’re making a decision after Season 5 ends, verify the current Kast season terms before comparing. The math above applies specifically to Season 5.
