I heard some hackers who hack others via ransomeware virus are asking bitcoins in return. So people are a bit worried and maybe that is stopping them, but that is no reason, hackers use USD also so stop using it !
No this is the reason why they are not using it, I even find this the stupidest reason you could thing.
I do think people keep away from it due to the bad name the bitcoin has these days, its still a investment right.
Yes, that is not the reason which stop people from using bitcoin as only those people are aware with it that hackers are trying to hack bitcoins who are experienced in the usage of bitcoin, and along with that they know well that if we do more security to our coins then their attempts will be failed.
