How to top up a card with crypto
Updated: 2026-09-27
Topping a card up with crypto means sending stablecoins straight to a card
balance instead of selling them on an exchange and waiting for a bank transfer.
The saving is not the fee — it is the days.
What to check before the first transfer
| Check | Why it matters |
|---|
| Supported networks | sending on an unsupported network usually means the money is gone |
| Which coins | USDT and USDC are not always both accepted |
| Top-up rate | 1:1 against the dollar is the honest baseline; anything worse is a hidden fee |
| Minimum amount | small transfers are sometimes ignored rather than refunded |
| Confirmation time | minutes on most networks, longer when the network is congested |
Always copy the deposit address from the app for **the exact network you are
sending from**. Addresses look similar across chains and the transfer will not
bounce back.
How it works here
alt.vu is a dollar balance with a virtual Visa Platinum card. You top it up with
USDT or USDC on TRON, BNB Chain, Polygon or TON, and spend in US dollars anywhere Visa works online. Issuing costs $25
once, there is no monthly fee, and we add 1% on top of each purchase. Sign-up
takes about two minutes and identity is verified with a passport.
The card is virtual only and does not work inside Russia.
Your balance is credited 1:1 — a stablecoin is already a dollar, and a provider
that takes a cut on the top-up rate charges you twice.
