What are the top risks for Bitcoin holders?
One of my greatest fear as a bitcoin holder, is when it totally looses its value together with other cryptocurrency. From a thousand dollar worth a piece to zero feels like a gold turn into a stone. I am also afraid that my wallet get hacked by someone and collect all my coins in it. I am also afraid about my laptop, cellphone and my wallet be stolen by somebody where all my private keys and passwords are located.
