Maybe right now cryptocurrency isn't looking great I just don't see why he thinks Bitcoin is a complete scam. Buffet hasn't really given any reason as to why cryptocurrency is a scam.
True, what he said is a speculation only. They wanted the holder release their bitcoins. I don't like hear that negative say, but I like to hear to make me laugh. For me? Btc is forever and the future. Keep holding, you can get a big profit for that.
