Like you said yes there are so many ways with which you teach your children about what bitcoin is. Rather I suggest schools have more important role in this regard.

Teachers can teach them what bitcoin is actually and how it works generally and then as you suggested children are given such online games. This all will make a better impact on their minds about bitcoin and they will love it when they become young.

As long as they have the capability to understand it we can teach them. In fact it is more easier to teach kids today because they are more engage to technology. They are very updated to everything. What we just going to do was explain what bitcoin is and how it works. In fact most of the users now here was just a student as I see in any thread.

I would be careful and might not even want to teach them because of the amount of exposure that will bring which might not be healthy to the development of a kid especially the advertisement that is being showed on faucets sites. So be careful.

Since we are now in the digital age this is a good way of using these cryptos. In this way, it becomes more sensible and the flow of knowledge is much more lighter given the fact that we are talking about kids here. Just make sure that they will have the proper guidance with this lessons for they can possibly be so interested to money that they will not prioritize their acads because of it. Proper guidance should be observed, adult assistance is a must.

In the process of developing children's financial businesses, we need to constantly teach him a lot of cutting-edge stuff.

If your child is less than 12 years old, they are still in the pre-operational and concrete stages of development. Their minds lack the ability to abstract and generalize, and rely more on intuitive concrete.

We can't get them to see the nature of the blockchain or bitcoin, and you can only explain the metaphor that is closest to the truth.

When the child understands the blockchain, you can easily explain bitcoin to him.

Correct. Kids are kids, they should have enjoy life being a kid. The right  time will come that it's their turn to learn and handle their own finaces, but for now let's help them feel that being a kid is worry free.

I think all the children should not be taught, but the lesson of such a free visit is needed, but any child can attend it, after having discussed with the parents whether it is necessary for him and his family or not.

I would say teach them through songs, games or cartoons. Though that would be definitely hard.
Teach them basic economics and trading through everuday situations and slowly teach them what bitcoin is. Let them know how to be wiser in earning and spending (mostly earning) money.

Yes, there is no better way than using games to introduce new stuff to kids. It's important to teach kids starting today about bitcoin and other digital currencies.
Minecraft can now be used to teach children about digital currency.
