$21.6M is all that's sitting on crypto cards.
We read the live stablecoin balance of ~580K card wallets across 7 chains. Almost all of them are empty — crypto cards are payment rails, not places people keep money.
85% hold ~$0 · median balance $0 · the money that exists is held by a tiny few.
The inversion
Half a million empty wallets — and a few hundred hold it all.
Every card wallet, grouped by how much it holds — richest tier first. The bar is each group's share of the total money. Notice the wallet counts next to it.
| Balance held | Wallets | % of people | Money held | Share of the money |
|---|---|---|---|---|
| >$10K | 267 | <1% | $7.16M | 33% |
| $1K–10K | 3,014 | <1% | $7.92M | 37% |
| $100–1K | 16,430 | 2.8% | $4.39M | 20% |
| $10–100 | 49,921 | 8.6% | $2.05M | 9% |
| $1–10 | 17,485 | 3.0% | $0.08M | <1% |
| $0 (empty) | 492,809 | 85.0% | $0 | <1% |
People don't keep money on crypto cards — they spend through them. The float that exists is a handful of whales, not a habit.
Why the exception matters
People hold money the moment it pays them to.
Every card spends down to zero — except Plasma One, where 87% keep a balance. The difference? Plasma's balance earns yield. Give money a reason to sit, and behavior flips from rails to bank account. It's not that people reject holding crypto — a bare card balance is just a dumb place to keep it.
By card
Funds held, card by card
Averages are whale-skewed, so the median holder is the honest "typical user". The bar shows the share of each card's wallets that hold anything.
| Card | Wallets scanned | Total held | Avg | Median holder | Highest | Holding |
|---|---|---|---|---|---|---|
Tria, Kolo, Avici, Ready & Tuyo — five cards on Rain's shared infrastructure. Their balances can't be split per brand (Rain keeps that mapping private), so we show the group. | 25,814 | $9.04M | ~$350 | $41 | $211,107 | 71% |
Yield-bearing balance you spend from — a checking account, not spend-down. | 10,832 | $5.07M | ~$468 | $92 | $83,041 | 87% |
| 344,040 | $3.73M | ~$11 | $40 | $91,000 | 13% | |
| 23,852 | $2.67M | ~$112 | $8 | $187,111 | 45% | |
| 4,831 | $600K | ~$123 | $34 | $40,333 | 21% | |
| 65,104 | $350K | ~$5 | $7 | $98,293 | 1% | |
| 32,111 | $70K | ~$2 | $99 | $4,900 | 1% | |
Custodial — this is funder wallets, not the card balance (KAST pools that off-chain), so it's directional. | 8,331 | $70K | ~$8 | $49 | $6,257 | 9% |
| Total | 514,915 | $21.60M |
EtherFi and Gnosis are excluded from the table above — they are credit cards that spend against collateral (staked assets held elsewhere), so no stablecoin ever sits in the card wallet. A zero balance is their architecture, not empty users; their cardholders are among the most active spenders we track — they just don't hold.
By chain
Where the money rests.
Plasma punches far above its size — 10.8K wallets hold as much as Base's 169K, because its balances earn yield.
Methodology
How we measured it.
We've identified ~900K card wallets and read live balances for ~580K of them (the crawler runs highest-value-first, so every large balance is captured; the uncrawled tail is low-value). The table shows 515K — the 580K minus 64K EtherFi/Gnosis credit-card wallets that hold nothing by design.
Balances are the live stablecoin holding (USDC/USDT/USDT0/DAI) across Base, Plasma, Arbitrum, Polygon, Tron, BSC and Scroll.
Treasury, aggregator and settlement-relayer wallets are excluded: a wallet with a huge balance and near-zero card activity is infrastructure, not a user. This filter removed millions in fake 'user' balances, including 21 Rain settler addresses.
Whale balances were forensically verified as real users — diverse token holdings, independent funding, no exchange or treasury labels — not infrastructure.
Custodial cards (RedotPay, KAST) pool card balances off-chain, so their users' on-chain wallets are structurally near-empty; their low share is the model, not poverty.
Balances are a point-in-time snapshot, refreshed hourly by our crawler. Averages are whale-influenced, so we show the median holder too.
