today I experienced an unexpected transaction from one of my wallets, all my assets were sold automatically, this is the first time I've experienced this, I didn't protect this wallet with a PIN and 2fa
can it be delayed after I use 2fa and PIN for all transactions?
If the transaction is in progress, then you can cancel via email, or without confirming the ongoing transaction. 2Fa and PIN are very important in an exchange, if you don't use them, it is very likely that transactions can be made, because there are exchanges that can make transactions without passing an email confirmation.
