On July 16, according to the Federal Election Commission's records on Monday, the founders of the cryptocurrency trading platform Gemini, Tyler Winklevoss and Cameron Winklevoss, each donated $250,000 to the Trump Super PAC. Earlier, on June 22, Trump's presidential campaign team returned part of the funds to Gemini co-founders Cameron Winklevoss and Tyler Winklevoss brothers because the donations they had previously provided (worth $1 million in Bitcoin) exceeded the statutory donation limit allowed by US federal law.
