That's the way you have to take to make a new wallet and make security quite difficult to break. But there is no way in my opinion to re-take what you have from the hacker. you just have to let it go what has gone from you.
indeed we have to give up and good advice for us to make a new wallet.
but even though we have made a new wallet, i think we still need to be vigilant and be careful when using it so that the same thing does not happen again.
There are some hacking incidents that i read before that they have recovered the funds that been stole by the hackers, those victims did seek some profesional help because the founds is large enough .
smaller funds can be easily forgetable because they can be easily collected . but you shoudlnt give up easily , you must still do something tho .
