According to a report by Golden Finance, based on Federal Election Commission data compiled by crypto market and blockchain analyst James Delmore and independently verified by CNBC, Gemini Trust Co. founders Cameron and Tyler Winklevoss are the biggest individual crypto donors of this election cycle, contributing a combined $10.1 million, with each brother donating slightly over $5 million.

The Winklevoss twins donated a total of roughly $1.7 million in bitcoin to the Trump 47 Committee, the fundraising arm of former Republican President Donald Trump, $700,000 to the pro-Trump "Make America Great Again" political action committee, $250,000 each to pro-Trump American political action committees, and $4.9 million to a bipartisan political action committee that supports cryptocurrency.
