There is nothing surprising in this story in the relationship between parents and children. Parents very often don't even suspect what their children are doing and may not know anything about their hobbies. There is only one solution - to keep your children's hobbies under control (until they reach independent adulthood) and instill the right skills for survival in this world (moral and ethical standards). And also that bitcoin is not completely anonymous (and most cryptocurrencies) and that it is completely unsuitable for their misdemeanors.

After reading this story,
BTC-haters will probably accuse bitcoin of being used for criminal purposes once again. In the story told above, the crime was committed by a person (young), not bitcoin. Bitcoin only unwittingly became an instrument of the crime.
From the story, it's very obvious that the fathers very ignorant about Cryptocurrency or modern tech else as a father he should've been able to monitor what his son was doing and how he makes money online, imagine if bybit didn't restrict his account which required his father to seek your attention, he would've still been deceived till this point, ignorance is really a disease.
You're right, haters would always look for a way to criticism the use of Bitcoin or make it seem like it's mostly use and creation was to support fraudulent activities but that's not true, the criminal is an adult and should be held accountable for his crime and not Bitcoin.
