hello @belemo,
I understand how you feel at this moment, some time ago from my poloniex wallet a hacker stole half bitcoins, this experience taught me that security in the world of cryptocurrencies is very important.

we should always be careful with our cryptocurrencies because they are digital money, I hope my dear friend you can overcome this difficult moment and see it as a very expensive lesson, I guarantee you that with time you will recover and now you will be wiser with your security.
