The twins gained initial fame from their legal dispute with Mark Zuckerberg over the founding of Facebook, and they invested a significant portion of their settlement into Bitcoin when it was trading around $10 in 2013. They became the first publicly known Bitcoin billionaires and have been prominent advocates for cryptocurrency regulation and institutional adoption.
