Cameron Winklevoss, the co-founder of Gemini exchange and a prominent Bitcoin investor, has challenged Barry Silbert, the founder and CEO of Digital Currency Group, to a public debate over the future of Bitcoin.

In an open letter published on Medium, Winklevoss accused Silbert of spreading misinformation and FUD (fear, uncertainty, and doubt) about Bitcoin through his Grayscale Trusts, which offer exposure to various cryptocurrencies, including Bitcoin Cash (BCH) and Bitcoin SV (BSV).

Winklevoss claimed that Silbert is trying to undermine Bitcoin’s network effect and brand by promoting these “inferior forks” as legitimate alternatives to Bitcoin. He also criticized Silbert for launching a “Drop Gold” campaign, which he said is a distraction from the real enemy of fiat currency.

Winklevoss argued that Bitcoin is the only true successor to gold and the only cryptocurrency that matters. He said that Bitcoin has the strongest security, the most adoption, and the most innovation in the crypto space. He also said that Bitcoin is the only crypto asset that can achieve global reserve status and challenge the dominance of the US dollar.

Winklevoss invited Silbert to a public debate on these topics, saying that he is willing to put his money where his mouth is. He offered to bet $1 million worth of Bitcoin on the outcome of the debate, with the winner donating the proceeds to a charity of their choice.

Winklevoss said that this is his final offer and that he will not engage with Silbert on social media or any other platform until he accepts or declines the challenge. He urged Silbert to stop hiding behind his tweets and face him in a fair and open discussion.
