Obviously, someone had answered already that US didn't banned Bitcoin or crypto in general.
Now to get their US Binance platform and to fully satisfy US regulations, they have partnered with this so called company, BAM Trading Services, it is a California based company, it is registered as a money services with US FinCen. As far as the effects, we still don't know it, it was just recently launched and remember that not all states supported Binance.US as well. I think you can't created an account if you lived in Texas and New York so that's a minus for Binance for sure. So we really can't say if it will push the price or not, but I guess the good news their market is really expanding and in the long run we might see the impact positively.
