This isn't a bad article, per say, they do have some things lacking but for the most part I think that this is actually pretty cool article which does touch on a lot of the issues that I've been seeing with Bitcoin over the past while. I think he does miss a lot of other uses for Bitcoin, since he claims that Bitcoin is used primarily for gambling and money laundering, and I know from experience that I do other things with Bitcoin, but he does make some valid points.
And I agree. There are many things with Bitcoin that may not really be perfect and that is just natural because Bitcoin is also evolving. As to its usage for gambling and money laundering, well, we have to understand that any currency can be used for that purpose so singling our Bitcoin may not really be fair. Hopefully, all of those valid points can be addressed by the Bitcoin stakeholders gradually.
