I would like to delete my account. I checked the help section, which instructed me to go to my profile and click on 'Delete Account' under the "actions" section on the left. However, I am unable to locate both the "actions" and the "delete account" link
You can't remove your account on Bitcoin but if you really want to do it then go and change your account's e-mail address and completely forget about this account.
That's the only way to delete an account otherwise you can't really delete an account on this forum. You can create a fresh e-mail for that purpose and then completely ignore that e-mail. I won't suggest you to use temp mails as those can be reused by others.
Only admin can delete the accounts but I don't think that admin has enough time to delete accounts of the users who create accounts and ask others that how to delete the account.
