Bitcoin has been bouncing back, after having spent much of 2018 below $4,000. There are many different theories as to why this is the case - the U.S. and China trade war, a possible wealth tax in the U.S., Facebook's introduction of Libra, and geopolitical tensions across the world.
"So crypto is alive and well these days, even if (like me) you reject the utopian predictions that it will somehow displace money as we know it. If we have had a hard time seeing the resiliency of the crypto space, it is because we are not used to thinking of futures that are radically different from the present. But those futures - for monetary institutions at least - now seem closer than ever before" - Tyler Cowen, Bloomberg
