Binance really seemed like an exchange that was trying to comply with the regulations and even follow sanctions initially. But then came allegations and investigations that Binance is helpful for evading the US sanctions, and it seems that Binance didn't do enough to prevent that from happening (and, judging from the article, sometimes even helped high-level clients to keep using Binance). What's good about this case is that the fall of CZ did not take Binance down. Binance will be supervised but will continue to operate, and 18 months isn't a big jail term.
Most of us are reading what the media is presenting to the table but there are more to things they feed the public, who knows if it’s Binance doing their thing to win the case or the Law enforcement doing what they know best.
Binance( the global exchange) was launched in the year 2017 and when they came around, the were operating accross all over the countries but later scams and fraud rates where at all time high that period because of ICO tokens that was taken place that time and Binance were pressure to register with US and do proper registration and implement KYC for everyone but they feel succumbing to US will jeopardize their customers from other regions and they might go to other places. So the idea of Binance US was introduced, they launched that in the year 2019 and asked all their US customers to withdraw all their tokens and move to the new specific Binance US.
Binance US was operating fine but with limited tokens and most of the things happening on Binance global wasn't happening there like the Laundpad IEO. However, because Binance has become a company in the US, they used that to hold them on the neck, it was even their pressure that made Binance to completely made KYC compulsory later in all the exchange. As if that wasn't enough, law enforcement claim Binance were laundering money with Binance US and many other accusations with Binance global and they were (CZ pleaded) guilty and fine, that's how the witch hunt led Binance to where they are today but do you really think Binance didn't do stuffs like that, I doubt.
As for CZ, he is still in the US and no access to the internet and I think Binance are been smart enough to learn from Sam.BF so as not to complicate his case but worry not, he will be free when the time comes. The US just want to have crypto on their palm and CZ and Binance been the leading exchange was their target and they have it under watch, let's pray they don't come for Bitcoin.
