Billionaire's trolling on Twitter made Bitcoin prices tumble
Billionaire investor Mark Cuban, who appeared as a judge on the show 'Shark Tank', in a series of tweets said digital currency Bitcoin is in a bubble. Cuban's comments caused a dip in Bitcoin's value, which fell 5% intraday. Following this, Cuban tweeted, "So testy. Lol. You know it's a bubble when a random twitter thread bounces the price."
