He is probably being truthful about being a fan of bitcoin, and I've no doubt that many of the facebook staff feel similarly, else why would they bother coming up with the idea to create Libra? It seems obvious that they think there's something special about cryptocurrency. Marcus is also correct about the stable coin aspect of why he thinks the regulators are giving them a hard time. The gov't doesn't have any problem with new altcoins being created as long as their value moves according to what the market dictates. But when a corporation is trying to create a new form of money that's based on fiat...yeah, that's a problem in the gov'ts eyes.
