My bitcoin is safe as always in my online wallet, i also think that it maybe stolen or hacked sometimes that is why i don't put it in just one account, i cashout some of my bitcoin and the other i put in my alternative bitcoin wallet also and i install antivirus and spyware to my pc for the best extra precautions.
That's a good way to protect your bitcoin from hacked or stolen. But It is not that easy to hack bitcoin or any other cryptocurrency.
