The guy is a business man he promotes gold, but the people is simply not stupid enough to keep buying imaginary gold any more! and that's why he is so annoyed by bitcoin's success, he has been predicting a collapse of the bitcoin market for years now, and he just cannot see that happening.
Now that bitcoin has passed the 4000 usd dollars barrier he had to come out and double down on his predictions in defense of his own passed statements.
Of course he was waiting for a mayor downfall of the market provoked by the blockchain's crisis and he was so ready to jump out and say "I told YOU it was juts a bubble".
But that didn't happened, so before the public realized the fact that he has failed on his last predictions he has to come out and shout out that he is still sure about bitcoin being a "tulip bubble" and this time he has come out with even dumber ideas such as "The businesses that accept bitcoin are not really interested in it, they simply want to help you to sell it" and his famous stupid statement of "Is not money because is not being used massively by the people" or what about this other "the only segment of society where it's used for something other than speculation is crime,".
So basically his problem resides on the fact that people prefer to invest in crypto rather than precious metals which is obviously his business.
And whats really annoying about him is his arrogance when he thinks that his opinion is so important that somehow is gonna cause fear on the public about cryptocurrencies, this why he repeats over and over the sentence "Ponzi Scheme" because the guy has this intention.
So F- you Peter we are gonna tell you what money is and not the other way bro.
