Gerald Cotten was a Bitcoin entrepreneur. Robertson didn’t know exactly what that meant, but she didn’t think she needed to. Cotten was smart, successful, and kind. Over the next four years, as his company, QuadrigaCX, expanded exponentially, Cotten and Robertson, twentysomethings in love, became wealthy beyond their wildest imaginings. They acquired property, bought yachts and planes, travelled to exotic destinations. So much money rolled in so fast that they occasionally ended up with huge piles of cash on their kitchen counter.
