Maybe  i could not see they cannot hack our wallet or maybe i can say yes,because for me hacker is have a different level and expertise  in terms of hacking system,but only things i can guarantee in our wallet that the maker of this have its own system of defense wall against the hacker or intruder,but sometimes the mistake is in our side,because there are phishing site who wants to get all our information ,so that they can hacked to our asset,so in order to avoid this,we must take  a safety precaution before we trust our information to some of site's,just like happen in parity wallet before the hacker hacked there wallet and some investor lost investment.
