I think it's a great idea to teach your daughter about investing and Dogecoin is the right choice
Have you read carefully? His daughter is still 8 years old. She is too young to learn about investing in Dogecoin. I don't think it is a great idea because it will be wasting time. It will be hard for her to understand crypto at that age. In addition, investing in crypto is very risky, it doesn't make sense to let children learning it.
Well that is your opinion. I have been teaching some kids about crypto and it is an enjoyanble experience. It's like playing with play money. Why should you teach the complicated parts if you can teach the basics and still get something enjoyable out of it? If you don't want to teach crypto to your child that is fine. But you don't yak and tell others what or what cannot they do with their money. We are all responsible adults and no one should be dictating here what we should do with our DOGE.
