I never lost any single Bitcoin nor altcoins. I quite few times heard and read that some people were complaining or remaining without funds from wallets. There should be taken some extra steps when you are willing to store your coins locally. A good antivirus with encrypted wallet is good way of protecting like me.
That's good to hear mate i lost bitcoin and its lots because it was my fault anyway i always playing gambling thats the reason why i lose so much bitcoin but i always get free bitcoin from signature campaign and im using that to play gambling i already saw some of our co members here in forum are complaining on some investment website.
