JP Morgan CEO Jamie Dimon still isn't excited about Bitcoin's potential. In an interview overnight he said he doesn't "really give a shit" about the cryptocurrency. Dimon called Bitcoin a "fraud" in September 2017. While its underlying blockchain technology is "real", he said overnight that he doesn't "really give a s…t" about the digital currency and can't see it rivalling fiat money. In September last year Dimon called Bitcoin a fraud that's "worse that tulip bulbs".
