when i came back i saw they closed my account with more then $500,000 wager.
He said He wagered $500K

^ But that is still a lot of money and though there is no clear statement of how much money was left on his locked account, I believed that the account that was close was don't have fund left as @DuckDice.io team stated above.
But I don't understand why they are locking inactive account instead of asking for verification, a 2FA, or any verification that have to prove ownership. Locking is a bit annoying when you contact support it takes time to respond.
