So sorry to hear this. Do not quit, persevere. We all lose some money, and then get very serious about Bitcoin. I hope it was not Millions. Get a NANOs hardware wallet or a Treznor. Use a USB drive for your PC wallets and keep it in a safe. John McAfee goes on and on about all the ways you can be hacked because his job is computer security. Learn all you can, and again, I am terribly sorry about your loss.
