I signed up for Binance.US about two months back. It’s legit but a very low quality offering. Support is just massively overwhelmed and unresponsive. But most exchanges are overwhelmed now so it’s not that unusual.
Same, I signed up when GME/DOGE both started spiking since I have DOGE laying around in a wallet. Getting coins into the exchange was easy enough and I can't comment on trying to withdraw but I can say the verification stuff is stupid-slow. I've provided info for all 3 tiers of verification and my account has sat in "pending" for over a month on the last step (first step was instant, second step took a week or so).
I can always buy BTC on coinbase and transfer them over then convert them to USD/(T) but that's not ideal.
