I live with strict parents and for me, as long my children not feel what i feel is already ok. Not means make them really free to do what they want. Rules maybe yes, but for a job or from what their income, as long it is not criminal i will support it. And although i am in crypto, maybe i will just tell them what crypto is, they interested or not it is their choice.
Crypto will probably be much more popular in the future than it is now and it is expected that many real businesses will adopt it as a means of payment even though it is currently facing regulation from many governments. In my opinion, teaching kids about the basics of crypto is probably the best way to prepare them for this modern era. I would, it would make them so much better than nothing.
