Yeah, they claim their operation is legal in our country and they even use the brazilian banking system and hire brazilians to work in the brazilian "branch" here, but the website and the support refuses to give legal information, such as company ID or legal address, which is mandatory by law to be easily accessible.
Binance seems like a good platform, but with shady stuff I never noticed until I searched for it, like the lack of information about their operations.
Recently they almost got into legal trouble in Brazil but they did provide information to the government regarding legal contacts, but to the government onlt, and that should be public, so they avoided getting banned here, but still, they are ignoring the laws and doing the bare minimum for the government not to ban it (apparently)
It is not as if they don't have the money or human resources, it seems like they just want to keep things shady and hidden for some reason...
