Circle’s transparency page makes its redemption promise and then repeats it in one word. USDC “is always redeemable 1:1 for US dollars,” the page says, followed by “Always.” Playtika’s Terms of Service promise the reverse for the coins in its games: they “can never be redeemed or cashed out” for money, goods or anything else of monetary value.
Most coin designs a crypto reader runs into sit somewhere between those two sentences. Sweepstakes platforms let one of their two coins out. Governance tokens leave only when another buyer takes them. Burn mechanisms shrink supply without promising anyone a price.
Where a design places its exit decides what the issuer must hold in reserve, what a holder has to prove before leaving, and how units finally disappear. This comparison covers those mechanics only and treats no coin or token as a way to make money.
Playtika Sells A License, Not A Balance
Playtika’s terms treat a coin as permission to play rather than property. “You don’t own Virtual Items,” the document says, and a player holds no rights in them beyond the license the terms grant.
The items work only in the game where they were acquired, and they “are not prepaid payment instruments.” Outside the United Kingdom and the European Economic Area, Playtika may end the license at any time, with no credit, reimbursement or refund for whatever was left in the account.
App stores give the design a commercial reason. Google Play bars apps that don’t qualify as approved gambling apps from letting people use real money, “including in-app items purchased with money,” to obtain a prize of real world monetary value. Apple’s guideline 5.3.3 forbids using in-app purchase to buy credit or currency for real money gaming of any kind.
The terms rule out cashing items out with Playtika or anyone else, so no market exists for a price tracker to follow.
A Court Still Found Value In Chips Nobody Could Cash Out
Big Fish Casino tested the no-exit design in court. Its Terms of Use said the virtual chips had no monetary value and could not be exchanged “for cash or any other tangible value,” yet players paid from $1.99 to nearly $250 for them.
On March 28, 2018, the Ninth Circuit ruled in Kater v. Churchill Downs that the chips still counted as a “thing of value” under the state gambling statute it applied. They were “a credit that allows a user to place another wager or re-spin a slot machine,” the court wrote.
Kater also pointed to chips sold on a black market and moved through the app’s transfer feature, but the terms banned that trade, and the court declined to count it. The value it found came from play itself.
That ruling read one state’s statute, and other courts can read their own laws differently. According to ClassAction.org, a $155 million settlement resolved lawsuits alleging that virtual chip sales in Big Fish Casino, Jackpot Magic Slots and Epic Diamond Slots broke gambling and consumer protection laws.
At A Sweepstakes Platform, The Coin For Sale Never Leaves
Sweepstakes platforms add a second currency and open a narrow exit for it. The coin sold in packages, usually called Gold Coins, stays inside like Playtika’s items, while the promotional coin, often called Sweeps Coins, cannot be bought at all.
Players collect promotional coins as a bonus with purchases, as login rewards or through a free request by mail, and each platform’s official rules set the playthrough and identity checks that come before a prize.
The design inverts a stablecoin. A USDC holder redeems the same unit that was bought, while a sweepstakes player can buy only the unit that never redeems.
Operators rely on the free route to promotional coins when they present the product as a sweepstakes promotion, a position that several state attorneys general and legislatures have rejected and that remains contested elsewhere.
A Stablecoin Issuer Owes Par Under Law
Stablecoin law turns redemption into an obligation. President Trump signed the GENIUS Act on July 18, 2025, after it passed the Senate 68-30 and the House 308-122, and it requires payment stablecoin issuers to back their coins one-for-one with reserves.
Those reserves must sit in a short list of assets, which a Georgetown Journal of International Law analysis says includes cash, insured deposits and Treasury securities maturing within 93 days. Issuers must also publish a redemption policy and may not pay holders interest or yield.
The law takes effect no later than January 18, 2027, and Morgan Lewis counted proposed rules from the Treasury, the OCC, the FDIC and the NCUA within nine months of the signing.
Europe moved first. MiCA’s stablecoin titles have applied since June 30, 2024, and Article 49 gives holders of e-money tokens a right to redeem at any time and at par value, with Article 49(6) barring any fee for it.
Circle France, which issues USDC and EURC in the European Economic Area, cites Article 49 in its redemption policy. Retail holders apply through a form, pass identity and transaction checks, supply an EEA bank account and should be paid within 5 business days unless the checks find discrepancies.
Tether’s Redemption Window Starts At $100,000
Even a promise of par passes through a gate. Tether’s fee page sets a $100,000 minimum for redeeming directly, charges the greater of $1,000 or 0.1% per redemption and requires a non-refundable $150 verification fee, and Tether alone decides which accounts it approves.
Circle’s US terms follow the same pattern. Only holders with a Circle Mint account in good standing can redeem USDC directly, a holder who is not eligible “is not entitled to redeem USDC with Circle,” and redemption requires identity checks tied to Section 326 of the USA PATRIOT Act of 2001.
Circle France’s policy even lists the exchange route first. Holders may buy and sell the coins on retail exchanges at any time, and the direct process serves those denied at an exchange or who specifically want to redeem with Circle France.
Sweepstakes redemptions also sit behind identity checks and minimums, but only the e-money token’s right to par comes from a statute.
Social Casino Apps Put The No-Cash Rule On The Download Page
Social casino operators explain their coin systems in the opposite order from Circle. Circle leads with “Always” and keeps eligibility in its terms, while game makers put the no-exit rule on the listing a player sees before installing.
Slotomania’s App Store listing calls the game “for amusement purposes only” and says it “does not offer ‘real money’ gambling, or an opportunity to win real money or real prizes based on game play.” DoubleDown Casino’s listing uses nearly the same wording and adds that playing “does not imply future success at ‘real money gambling.'”
Sweepstakes platforms have more to explain, since one of their two coins can leave and the other cannot. Reading those explanations platform by platform, alongside independent coverage in the GamingToday social casino guides, shows where each operator draws the line between the coin it sells and the coin it lets out.
The sentence worth finding on those pages names the coin that can leave and the checks that come first. A page that names none describes a license in the Playtika mold.
For One Weekend In 2023, USDC Had No Issuer Window
USDC holders lost the issuer’s exit for one weekend. A Federal Reserve staff note published in 2025 traced the days after Silicon Valley Bank failed on March 10, 2023, when Circle said it could not withdraw $3.3 billion of reserves, about 8% of the total, from the bank.
Circle said issuance and redemption were “constrained by working hours of the U.S. banking systems,” so the primary market went quiet until Monday. Hourly trading volume reached nearly $2 billion on March 11, the price bottomed at 86 cents, and the peg fully returned once Circle resumed redemptions on March 13.
Governance token holders face that weekend’s conditions all the time. No issuer promises to buy UNI back, so a holder’s exit price depends on the bids resting in an order book or the liquidity in a pool.
Coinranking’s guide to reading a crypto depth chart shows how a market sell order consumes bids at successive prices, which is how a thin book turns a large exit into a lower average fill.
Burns Remove Supply, But Only Some Pay The Holder
Burns shrink supply from the other direction. Ethereum’s London upgrade introduced EIP-1559 on August 5, 2021, and the protocol has burned each transaction’s base fee ever since, leaving only the tip for whoever produces the block, as ethereum.org’s documentation on gas explains.
BNB burns on a formula instead. Its 36th quarterly burn destroyed 1,615,827.795 BNB, CryptoBriefing reported in 2026, with the amount set by the average BNB price and the number of blocks produced on BNB Smart Chain. Burns will continue until half of the original 200 million supply is gone.
Uniswap turned its burn into a conditional exit. Governance approved the UNIfication proposal on December 25, 2025, by 125,342,017 UNI to 742, and the 100 million UNI treasury burn went through on December 28, Cointelegraph reported.
Protocol fees now collect in a contract called TokenJar, and only the active releaser contract can withdraw from it. The Firepit releaser hands the collected assets to whoever burns a UNI threshold that governance sets, so the caller receives whatever the jar holds, not a fixed price.
Set side by side, the exits differ less in what they destroy than in what they return:
| Exit | What Leaves Circulation | What Comes Back | Who Can Trigger It |
| USDC Redeemed At Circle | The redeemed USDC | $1 per coin, less any fees | Circle Mint account holders, or eligible EEA holders through Circle France |
| Ether Base Fees Since 2021 | The base fee on each transaction | Nothing, since the tip goes to the block producer | The protocol, automatically |
| BNB Auto-Burn In July 2026 | 1,615,827.795 BNB | Nothing | A quarterly formula |
| UNI Burned Through Firepit | A UNI threshold set by governance | Assets collected in TokenJar | Anyone who burns the threshold |
| Playtika Virtual Items | Coins spent in play | Further play in the same game | The player |
Redemption at par is the only row where a fixed amount of money comes back, and it is also the only row that needs reserves behind it.
In A Social Casino, Play Does The Burning
Social casino coins leave circulation the way the table’s last row suggests, one spin at a time. DoubleDown Interactive’s annual report for 2025 says control of its virtual currency “transfers when the virtual currency is consumed for gameplay,” and the company recognizes revenue as players use it up.
At each period end, DoubleDown estimates how many days the outstanding currency will take to consume and defers that amount “as a contract liability.” Playtika’s 2025 annual report recognizes consumable items as they are consumed, “usually up to one month,” and both companies found that players generally do not buy more currency until they have substantially used up what they hold.
A purchased game coin is therefore a short-lived liability that play extinguishes, while a USDC token that circulates for years stays a claim on a dollar, with reserves behind it until someone redeems it.
Sweepstakes platforms sit between the two, because play consumes both coins while the promotional one can still become a prize. State action against that prize route kept reshaping platform rules, and GamingToday posts its coverage of those changes to its X account.
