As Upgrade00 mentioned, CZ was only sentenced to 4 months in prison and he is serving it, and so far, you can also feel things for yourself about BNB or Binance. There doesn't seem to be any serious effects or troubles happening to them.
Before the sentence, the price of BNB dropped slightly. But it immediately recovered from $556.20 to $570.60 after the sentence. Changpeng Zhao (CZ) has already stepped down as the CEO and four months is not a long time to affect the company immensely. He was just lucky to have just a few month's sentence because such a crime could lead to as much as 10 years in prison.
But if you are investing in BNB then you need to know that BNB as well as other altcoins like Solana, Ada...any altcoin, they will have risks and there are many risks that need to be considered, not just their creator. Even if they are still run and led by CZ, there is no 100% guarantee that BNB or Binance will not encounter any problems. The cryptocurrency market has many potential risks that we can never predict, so always have a suitable investment plan for any coins.
A lot of people have so much confidence in Binance. Some people believe that the company is founded on a solid financial foundation that will make bankruptcy difficult. However, they should be aware that no centralized platform is trustworthy. They can easily be attacked by the government or can be mismanaged.
