Calling bitcoin a fraud is a good way to get some publicity these days. That is what it amounts to. Belfort is just looking to get his name in the headlines again. It is good business. I bet he sells a ton of training programs because of this.
As for Bitcoin itself, it isnt a fraud. There is no way something that will be accepted by 250,000 places in Japan is a fraud. Houses are being bought with bitcoin.
I could see someone saying it is overpriced but that doesnt get headlines. Words like fraud, ponzi scheme, etc... are what get the publicity. A guy like Belfort is a media whore...looking to move more product.
Thanks for the post.
