For sure almost everyone is afraid of hackers. Who would like their hard earned money be in hand of others against their will by the way? But then our wallet according to some who have more knowledge is almost impossible to decrypted and hack even by genius computer geeks (well still possible but might have a very minimal account) so that reason make me feel comfortable enough that my funds are safe as long as I keep my PKs secret and be careful logging in to any site that required my wallet's credentials.
