The largest ICO in the history of the cryptocurrency market — the Block.one project, which raised $4.2 billion for EOS in 2017-2018, remains one of the most significant. The founders — Blumer, Pierce, and Larimer, attracted investments from Galaxy Digital, Founders Fund, and Bitmain. After the ICO, the company was acquired by major billionaires, and its assets reached around $3 billion, including $2.2 billion in fiat assets and 140,000 bitcoins. Despite criticism and lawsuits, Block.one continues to play an important role, having created the Bullish exchange for institutional traders, investing nearly $10 billion in it. The Bullish IPO is expected in 2025, which will be a landmark event. Over the years, the company has gone through splits, rebrandings, and price declines, but remains one of the key players in the crypto space, demonstrating how large ICOs can transform into sustainable businesses.
