USD at Rollbit: a dollar floor for stablecoins, and no fiat article
Rollbit is the clearest case of the dollar used as a ruler and nothing else. Its article on deposits and withdrawals names the minimum for stablecoins in dollars, and the minimum for every other coin in that coin's own unit.
One article, changed in mid-August 2026, and a look through the help centre for anything on fiat. We found nothing.
What does Rollbit print in dollars?
“Stable coins all have a minimum deposit of $5 USD”, and the list under that line names USDC, USDT, DAI and PYUSD. The withdrawal half of the article gives stable coins a minimum of $5 as well and names USDC and USDT. For Bitcoin, Ether, Solana, Litecoin and the rest the same article gives the minimum in the coin: 0.0001 BTC, 0.002 ETH, 0.05 SOL, 0.01 LTC.
The article is blunt about the consequence of going under. Deposits below the minimum will not credit and cannot be recovered by support. It also says no fee is charged on deposits and that the sender pays the on-chain cost.
Why can one dollar figure serve four different tokens?
Because their price barely moves against the dollar, five dollars of any of them is close to five tokens, and a single line can cover the whole group. Bitcoin's price moves enough that a fixed dollar floor would need rewriting all the time, so the minimum for such coins is fixed in the coin and the dollar figure disappears. This is the plainest use of the dollar as a unit: it is where an operator writes a number that has to stay true.
Does Rollbit say anything about fiat?
We looked. The help centre's own lookup for the word fiat returned no article, and the deposit articles we read describe coins only. That is an absence in what we could read. It is not a statement that Rollbit refuses card or bank payments, and it would be wrong to write it as one.
Where to confirm the floor
The article itself says each figure can be verified in the cashier, and gives that as the place to look. A floor written in dollars is easy to remember; before sending, check that the cashier shows the same one for the coin you hold.
