I think that when children hit an age 13-15 and become teenagers, parents not totally stop monitoring their activities, but do that very lightly. Children build some trust or show that they are smart or at least use their mind before doing something, so parents partly let go parenting and let children learn and experience world themselves.
Until the children have grown up to become adult, they still need our guidance. We have to keep telling them how to navigate life until they're 18 that's what I think. We can reduce in the guidance but not to stop. Unless it's the kids using Bitcoin as cover up for their crimes but when anyone talks about Bitcoin, it should be investing or trading and not anything bad because that isn't Bitcoin. Bitcoin is good and has nothing that you can say is bad when investing in Bitcoin. Some scammers have found ways to scam people by asking for payments to be made in Bitcoin. This isn't investing in Bitcoin either hence children are getting cleaver with their tricks but we have to develop new ways of dealing with this problem coming up.
