It is fair or unfair sentence for CZ, depends on each person and their stance on it.

I believe there is no place in the world can give us completely fairness but from CZ case, I see it looks good that CZ still got supports from the judge Richard Jones.

How Changpeng Zhao's 'Good Guy' Reputation Secured a 4-Month Prison Sentence

Is CZ a good guy or bad guy?

Again, there will be different thinking among us on it but I imagine that if CZ is sentenced in another country, like in China, North Korea for example, he will be sentenced to death if the government want to do that. In the USA., it's simply impossible.
