binance is segregating their user base, banning USA traders. so the liquidity on binance.com is about to take a huge dive. this is actually a great time for bitcoin.com and blockchain.com to launch their exchanges.
nobody is boycotting BCH.
You think the US chaps are the only people who have been trading on Binance?
You must think this is still 2009-2011

Banning USA traders and those from other countries was the best thing binance could do to play safe from the Legal point of view.
Do you have any idea how much the SEC and other bodies have been witch hunting Exchanges and other crypto related services that were serving even US residents? or you are just gullible and think that they just shut down their service all of a sudden because they just don't want US resident?
As for Bitcoin.com and their exchange... those are just the last kicks of a dying horse
