In order to clear your bet history, navigate to the My Action tab, then click the Settings icon in the top right corner. 
Once you're within the account settings, click on the Clear Bet History option, then a pop-up will display to confirm the action. Please note, Verified bets cannot be deleted, so this action will only clear your Unverified betting history and once this action is completed you will not be able to recover these bets.
