Some casinos charge, or eventually empty, accounts that nobody uses. The rules come from each casino's own terms, and they differ on the thing that matters most: what counts as using the account. Before you leave money in an account you've stopped playing on, check when charging starts, how much it takes, whether the rest can be forfeited, and whether logging in is enough to stop it.
We read the English terms of four casinos on 6 October 2026: BitStarz, Flush, mBit and Bitz. This guide describes what those documents allow; we didn't hold dormant accounts or watch a fee being charged.01020304
What the terms say
Casino | When the clock runs out | What counts as activity | What the terms allow |
|---|---|---|---|
BitStarz | Six consecutive months | Logging in or out | A monthly fee of "a minimum 5 EUR" while the balance is positive (terms §13, last updated 25 June 2025) |
Flush | Twelve consecutive months | Logging in or out, using the service or betting | €5 per calendar month while the account is in credit; if less than €5 is left, the fee is all of it (terms §7) |
mBit | Twelve months to "Dormant", 36 to "Abandoned" | A deposit, a withdrawal or a bet | At 36 months, "any account balance will be forfeited minus administrative fees" (terms §12.1, last updated 9 March 2026) |
Bitz | No dormancy clause | — | No inactivity fee in the terms we read; someone who wants to withdraw from a dormant account is told to contact customer service (terms, last updated 19 August 2026) |
These are four examples, not a survey of the market, and the terms for your country or account can differ. Flush's page shows no update date.
Logging in doesn't always reset the clock
BitStarz counts logging in or out, and its terms say it stops charging "if your account is reactivated or the account balance reaches zero", without saying how an account is reactivated. Flush counts a login, a logout, using the service or a bet, and says you "will always have the option to log in and withdraw your funds".0102
mBit is different. Its account becomes dormant if you "have not made a deposit, a withdrawal, or placed a bet/wager for a period of twelve (12) months", so logging in to look at the balance doesn't count. Neither of the two activities that aren't bets comes free: under its terms a deposit has to be wagered before it can be cashed out (once on slots, ten times on table games), and a withdrawal can carry transaction costs if your bets since the last deposit add up to less than three times that deposit.03
Notice, and what happens to the last few euros
BitStarz can take its first fee at the beginning of the month after the account becomes dormant, and says it will tell you by email; the clause gives no number of days. The wording "a minimum 5 EUR" sets a floor, not a fixed amount, and the fee can be charged "as long as Your account has a positive balance".01
Flush's terms say: "You will be notified that we will start charging you the fees on the eleventh month of inactivity"; the fee itself applies after twelve consecutive months. Once less than €5 is left, "the Inactive Account Fee shall comprise the remaining funds in your Account". mBit emails after the eleventh month that the account will be set to dormant in 30 days; there's no monthly fee in its clause, but at 36 months the account is "Abandoned" and "any account balance will be forfeited minus administrative fees".0203
How long a balance lasts
Casino | Charging starts | An untouched €100 is gone after |
|---|---|---|
BitStarz | After six months without logging in or out | 20 monthly fees at most, since €5 is the minimum |
Flush | After twelve months without activity | 20 monthly fees of €5 |
mBit | No monthly fee | 36 months, when the balance is forfeited minus administrative fees |
Counted from the last activity, that is about two years and eight months at Flush and no more than a little over two years at BitStarz. The figures assume no deposits, bets, withdrawals, other charges or currency conversion. A larger balance lasts longer under a flat fee; under mBit's clause the size of the balance doesn't change the date.010203
Taking the money out isn't always free either
If you plan to withdraw an untouched balance before any of this starts, check the withdrawal rules too. Bitz's terms say: "There are no withdrawal commissions if you roll over (wager) the deposit at least 1 time. Otherwise we are entitled to deduct a 8% fee with minimum sum of 4 euro (or equivalent in your account currency) in order to combat money laundering." mBit's let it charge "the costs of transaction processing" on a withdrawal when your bets since the last deposit total less than three times that deposit. BitStarz's say a deposit must be played through at least once before it can be withdrawn, and Flush's that any deposit "must be wagered at least once in full to be eligible for withdrawal". Small balances can be stuck as well: Flush and Bitz set a minimum withdrawal of $10 and €10 per transaction, except when you close the account.04030102
Don't place bets just to avoid a fee or meet a play-through rule. Ask support, in writing, how an unwagered balance can be returned and what it will cost. Our guide to how crypto casino withdrawals work covers the stages a withdrawal goes through.
What to ask if a fee has been taken
Keep the terms you can find and every message. Ask support, in writing, for:
the clause and the version of the terms it applied, and the account currency;
the last activity it recorded, the date the account became dormant and the date of the first fee;
a statement of each deduction: the balance before it, the rate or amount, any conversion and any forfeiture;
the notice it says it sent, with the date and the email address used;
how to withdraw what's left, or ask for a review, without placing a bet.
A short message is enough:
Please tell me which dormancy clause was applied to my account, the date of my last recorded activity and of each notice, and a statement of each deduction. Please also tell me how I can withdraw the remaining balance and ask for a review of any deduction without placing a bet.
If you've excluded yourself from gambling, ask support to handle the balance without reopening access to play; don't lift an exclusion to reset an inactivity clock. Our guide to self-exclusion covers asking for a balance during an exclusion. If support can't explain a deduction, make a formal complaint with the documents attached; our guide to a casino refusing to pay covers getting the decision in writing and where a complaint goes.
When a casino closes instead
A closure sets its own deadlines. Bitsler's homepage, read on 6 October 2026, said it was closing and no longer accepting bets, asked players to withdraw their balance by 7 October and said accounts would be permanently closed on 8 October. It told anyone left with a balance after the closure to contact support@bitsler.com before the end of 31 October to claim it.05
What we couldn't check
We couldn't read current terms for CoinCasino or Donbet when we prepared this guide, so they aren't in the table; that isn't evidence either way about what they charge. Mega Dice is left out for a different reason: on 6 October 2026 its terms page gave us two different documents in different sessions, one with an inactive-account fee and one without. If you hold a balance there, save the version of the terms you're shown.06
