I woke up on the morning and see -175$ ..
i ran malware byte and found 0 viruses.
no one could know my password.
beware of this site. terrible day for me.
Not only malware's can steal your passwords. Did you use same username and password on some other sites as well?
Did you protect your account with a 2fa function?
If you not protected your account with 2fa function then mostly someone else hacked your account, not blockchain.info guys. They are making tons of money why they will go for these small amounts.
