Article is not bad and also not saying wrong anything but still in the article we are seeing that only negative things are written and nothing is about positive views.
If any newbie who wants to enter in the Bitcoin field will surely exit it before to enter in because he will see that nothing is good .
So I think the author of this post should edit this and also mention the advantages of the Bitcoin .
Because beside all types of bad things like gambling , money laundering and use of Bitcoin for bad things deals in drungs , we have some better options  like , Bitcoin is solution of black money also , we can send worldwide money with more charge , we have security more than bank money , it can't be destroyed by anyone .And also cloning for this type of money is impossible​ and we are only the owner of our money , there is no one between the sender and receiver of the money so 100% safety with our money .
