So he was a hater before but now it seems that he recognized that bitcoin has potential and it can be a store of value. According to his statement it is like he acknowledge the bitcoin but he used the word "maybe" so he is still not sure about in his statement. I think he said that word "maybe" in order to not eat his own words that he rant in the previous years. The only good thing is another wealthy person acknowledge the bitcoin unlike other billionaire like Warren Buffet who said that he will not be interested in Bitcoin in any circumstances.
