Doubt it'll be anything beneficial for the community. It'll just be a poorly coded exchange that'll try to trick their customers into buying more BCASH instead of BTC. I'm personally really curious to see some stats behind Roger's first trick (
https://buy.bitcoin.com/) about how many people bought BCH compared to BTC, and how many people got tricked.
I'm also curious as to who in their right mind would trust Roger Ver with all their KYC information or to hold their coins for them.
Probably the same people who now think BCH is better and popular then BTC after Roger. I personally wouldn't touch the exchange with a 5-foot pole.
Since the exchange will operate within the bitcoin dot com portal, I'm pretty sure that we can expect Bitcoin to be referred to as Bitcoin Core. Another thing is that he will pair BCH to other coins and ignore the BTC pairs.
This is another thing that I was thinking about. I would reckon that Roger would pair alts to BCH, not BTC, and treat BTC as an alt, whilst treating BCH as the mainstream crypto.
I think Blockchain.com is trying to bring in more revenues. Despite being used by tens of millions of cryptocurrency users, Blockchain.com is not a profit making venture. Their wallet business doesn't bring in any revenues. So they may be trying to capitalize on the user-base to get some cash. But opening an exchange is not child's play, especially after so many exchange hacks.
This is bitcoin.com. Not blockchain.info.
