Your selected wallet balance, displayed fiat equivalent and available withdrawal amount are different views. Changing the display currency does not convert your cryptocurrency.
What each figure means
Selected currency: the balance you have chosen to view or use.
Fiat display: an indicative conversion of that balance into the display currency. The equivalent can change as exchange rates move.
Playable or available balance: the amount the relevant game or wallet flow permits you to use.
Withdrawable balance: the amount currently available for withdrawal after the applicable account and balance requirements.
For example, changing a BTC display from USD to EUR does not sell the BTC or create a EUR deposit. Selecting a different coin in the wallet opens that coin's separate balance; Housebets does not provide an in-account crypto swap.
When comparing a transaction
Check the original coin amount, the transaction's time and the currency used for the bet or payment. Do not compare today's converted balance with a historic converted payment as though the exchange rate were unchanged.
Reward-claim currency is a separate preference from wallet selection and display currency. Review the currency in the actual claim flow.
If a figure looks incorrect, tell support which screen, currency and transaction you are comparing. Use the withdrawable figure for a withdrawal question; a cash-balance label alone does not establish withdrawal eligibility.
