Stablecoin Casinos

A casino credits a deposit in the coin that was sent, and every stake, win and loss is then counted in that coin. The number of coins changes only at the tables. What those coins are worth changes with the market as well, from the moment the deposit is credited until the withdrawal is sold or spent, so a player can end an evening level in coins and behind in dollars, or the other way round.

Three measures describe that second movement. Annualized volatility condenses every daily price change of the year into a single figure: the higher it is, the wider the daily swings, up and down alike. The count of days over 5% is how many single days took the price more than that far from the previous close. The worst 30 days is the deepest fall over any month-long stretch, the figure that matters most to a balance left behind after the last session.

Ordered by annualized volatility, from the calmest coin of the year, TRX, to the wildest, ADA. Days are counted out of the whole twelve months, up or down, close to close. The three dollar tokens are left out here and compared on their own measure further down the page.

For the length of one sitting, price risk is modest on most coins. Taking each four hours of the year in turn, about as long as a long evening at the tables, an XRP balance moved by more than 2.12% one time in ten and a Cardano balance by more than 2.56%. Only once in a hundred such stretches did the price shift Cardano by more than 5.62%, and TRON by more than 1.77%.

A week is a different matter. A fall of more than 10% within seven days, rare over a few hours, became an ordinary event: it happened in 13.4% of all seven-day spans for Solana and 19.8% for Cardano, against 0.3% for TRON.

In short: Over one evening the coin moves a balance far less than a run of results at the tables can; left at the casino for weeks, the coin's price becomes a second bet of its own.

Over a month only the worst case is worth planning for. A balance left untouched through the wrong 30 days lost 56.8% of its dollar value in Bitcoin Cash and 46.0% in Solana, and even TRON, the calmest of the volatile coins, gave up 16.5%, whatever happened in the games. That is the case for withdrawing winnings rather than parking them, or for holding the balance in a token built not to move.

A dollar token does not swing; what can happen is a slip, a day on which the market values it a little above or below the dollar it stands for. The furthest close is the largest gap between any daily closing price and $1 during October 2025 to October 2026, in either direction, and the middle column counts the days on which that gap passed half a percent.

It removes the price. A balance in USDT or USDC stays worth almost exactly the number of dollars the cashier shows, whether the withdrawal leaves tonight or next month.

It leaves the house edge. A game keeps the same share of each stake whatever coin the stake is counted in. Dice advertised at 1% keeps 1.0099% of every bet in USDT exactly as in Bitcoin, and the originals odds guide works out what each of those games returns.

It leaves the network fee. A stablecoin is a token carried by some other chain, and moving it costs a fee in that chain's own coin: TRX for USDT sent on TRON, ETH for any token sent on Ethereum. What each network charges, and why, is covered in the networks and memos guide.

It adds an issuer. A dollar token holds its value because something stands behind it, either a company holding reserves or a protocol holding collateral. If the market came to doubt that backing, the token could trade below a dollar for days. A stablecoin swaps the price risk of a volatile coin for that risk instead, which is far smaller in an ordinary year but is not zero.

The three dollar tokens at casino cashiers differ less in price than in what keeps them at a dollar, and in how many casinos take them.

• USDT, issued since 2014 against reserves its issuer holds, is in the cashier at 59 reviewed casinos and travels on more networks than any other token, with TRON the usual route at a casino.
• USDC, issued since 2018 by a US company that publishes regular reports on its reserves, is taken by 40 of them and no longer runs on TRON, where its issuer ended support in 2025.
• DAI has no issuer to redeem it: it is minted against collateral locked in smart contracts, appears at only 11 casinos, and drifted furthest from the dollar of the three over the year.
