user-1: You are a law-abiding citizen and you have no idea how the bitcoins that you own now were used before. However, there is always a chance of getting "dirty" bitcoins that were used by criminals to buy drugs or weapons, or were used in money laundering.
What to do if the crypto exchange has frozen your account?
How many cases have there been that the exchange has frozen "illegal" bitcoins?

user24925: If an exchange decides to seize your Bitcoin, that's a civil matter between you and them. It happens not infrequently, as most exchanges use tools with questionable reliability to reduce their perceived risk. Generally speaking as a regulated business, it's their job to attempt to reduce any instance that may be money laundering or identity theft.
