Yeap, this is definitely most likely. Unfortunately for the Americans, it looks like the coins/tokens that would be able to trade will be very limited. Binance Jersey is pretty much only limited to BTC/ETH/BNB/FIAT pairs. The US version is most likely to be the same.
i see two possibilities here.
1. binance is segregating USA from international customers the same way bittrex did with their international platform. the reason bittrex did so was to comply with the SEC by ceasing to offer securities to americans. as a result, USA customers on bittrex don't have access to most IEO offerings + a few dozen security token markets, but we still have access to hundreds and hundreds of altcoin markets.
2. the binance jersey route. this doesn't make as much sense to me but is obviously possible. i don't see why binance would bow out of the USA market like that if bittrex and poloniex aren't going to.
