A 'trending topic' is quite a novel way to describe bitcoins model and agenda. Bitcoin was a trending topic a couple of years ago, it is now much more that a hot topic.
No one deny that he did not receive money. There is no scam in bitcoins if you have the bitcoins in your wallet it is 100% yours.
This is inaccurate, there is scam in bitcoins, and your wallet can be hacked amd your assets stolen. Never 100% trust any system or technology. Just maintain the highest level of security.
