So that's it they can do if they know my ip. Can they harm anything else because i am too much afraid now.
They could find information on where you live and your ISP, but a DoS attack is probably the most destructive thing they could do to you. If you don't have an unlimited internet plan, it can cost you quite a lot in bandwidth.
Thank god my internet connection is Unlimited and i can change the ip of my connection in free or with a Worthless fee
Can attackers steal the details of my login of any website which i work on like i have saved the details of login of bitcointalk in my computer so i don't have to type my username and password again and again ??
