The confusion might have been caused by the fact that you didn't post the entire address first as the last part is clear giveaway:
BAM Trading Services, Inc. One Letterman Drive, Building C, Suite C3-800
that's because they list only "suite C" in their FINCEN registration.
I'm not going to copy-paste all of them but you get the idea, approximating the search results there are about 50 companies located in that building dividing the floor room by that and it's well below your average Subway , if we say there are double the number than the space goes below your one-bedroom apartment, not enough for a rat to get claustrophobia but enough for a chipmunk.
you listing a few companies who also have offices there (yes, that's the point of office park!) doesn't prove your point.
what matters is they have a physical presence for legal service, widely known executives located in the USA, and legal registrations in a jurisdiction that can actually come after them in both civil and criminal court. literally none of that applies to binance.com. all of it applies to binance.us.
your assertion that "binance.us has a small office (something you can't even begin to prove) so they must be illegitimate" is rather uncompelling. if you feel the need to keep taking about square footage as a measure of business legitimacy, your points will fall on deaf ears.
As for the binance.com ≠ binance.us , that's just hilarious.
Is binance,us run by CZ's good twin or what?
we're talking about legal jurisidction. binance.us is subject to american legal jurisdiction. binance.com is not.
if you want to sue binance.us, you easily can, assuming you have a case. if you want to sue binance.com........lol, good luck even finding out how to serve them, let alone enforcing a judgment!
I remember I had the same discussions with other users when they were trying to tell me how Binance moving to Malta will change things how Malta will get millions in return in taxes and so on and on, and they had the same arguments, fully regulated, office, people working there, people never learn! Binance fleeing from country to country and jurisdiction to jurisdiction is more predictable than the seasons these days.
binance never had any legal presence in malta. they were just lying to everyone. they never registered any entity there. of course they wouldn't pay taxes there or be subject to EU jurisdiction.
in contrast, you can pull up binance.us's registrations. they openly operate from the USA, they are legally registered in the USA, they openly serve american customers---good luck to them if they are trying to dodge USA legal jurisdiction!
