How are you going to prevent the underage gambling?
How an underage person is going to buy bitcoin?
All the exchanges who accept fiat to buy bitcoin require KYC and if they see a minor the exchange is just going to close the account
I have seen adults get scam with P2P exchanges so the probabilities of an underage using a P2P exchange is low
Also is the responsibility of the parents to see what their child do online they can also be accessing adult sites
Well, you are very right, and I agree that it is indeed the duty of the parents to make sure of what their under-aged wards do online, personally, if not that the world we live in today have really changed, I don't see what or why an under-aged should even own a smart phone in the first place.
There are several under-aged gamblers in my area here, how do they buy bitcoin, or any other type of cypto? They simply register and pass kyc on the exchange using a document belonging to an older relative who is not into crypto, and this are the type of persons who always avoid casinos where kyc is mandatory, so in as much as I agree with you, i think that question is very important.
