Bitcoin.com chief executive Roger Ver has issued a $1 million challenge to F2Pool owner Wang Chun, who has claimed at a blockchain conference in Hong Kong that Bitcoin Cash “will be short-lived.”

The two executives were part of a roundtable discussion at the Bitkan-hosted 2017 Shape the Future Blockchain Global Summit, debating on the potentials of Bitcoin Cash versus the original Bitcoin. For his part, Wang said Bitcoin Cash will be abandoned soon, or as early as November, when another hard fork is expected to happen.

“Bitcoin Cash will be short-lived compared with earlier attempts because we will soon have another one coming very soon… after SegWit2X is introduced,” Wang said.

The F2Pool co-owner’s comment caught the ire of Ver, a confessed fan of Bitcoin Cash, prompting him to issue a bet.
