If you would like to turn off your Bitcoin autowithdrawals, please scroll down in your dashboard to the autowithdrawal section.
Then, click on the name of your wallet. That will bring up a list of your current withdrawal addresses. Please then delete the address associated with your auto-withdrawal plan. (Note: If you only have one address currently listed you will need to add another address before you can delete original).
Once you have deleted the original address associated with your autowithdrawal plan, your autowithdrawal plan will turn off.
