On November 4th, Andre Cronje, co-founder of Sonic Labs (formerly Fantom), replied to the message that "Coinbase CEO Brian Armstrong said that the platform does not charge any fees for listing," saying, "Binance does not charge a listing fee, but Coinbase has repeatedly asked for a fee and quoted $300 million, $50 million, $30 million, and the most recent offer was $60 million. I have not signed a non-disclosure agreement, so I am more than happy to provide relevant proof (the asking price is from multiple employees/departments at Coinbase, and has been made via email, Telegram, and Slack over the years). Coinbase can argue that this is not a listing fee, but an Earn Fee, but this will still translate into the listing cost of the project."
