I saw many people's account are hacked any how.My question is how can anyone hack accounts? And how we can protect our accounts? I don't know if this topic should be written here but i really need these answer.
There was a database leak in 2015. My guess is most of these hacks are related to this database leak.
That, or because other things that may happen. Mostly because of password breach, not because a brute force breach, more like because of the owner of the account fault. Using public wifi while accesing bitcointalk account, using others pc/laptop to access the account, phising site, extension on browser, same email same password, etc. It is kinda hard to know why though.
How to protect it? I guess there are many guides in the beginner section.
