"...they will come with a bad ending..." In Buffett's mind they will because when the next president comes into office after the current one, he will wrap around them around his finger like he did the previous presidential administration, and make sure of their collapse. Of course he hates cryptos. He also hates oil pipelines, locally owned newspapers, all sodas except Coke, all department stores except Wal-mart. But he really likes CSX (train transport co moving oil instead of pipelines), his new media conglomerate (he started buying up local newspapers so he could write his own news), Wal-mart, Mcdonalds, and everything else he has in his portfolio. He hates cryptos because he doesn't understand the sentiment behind them. He will not buy something he doesn't understand. I would not at all be surprised he changes his tune within a few years. Great post @sandalphon!
