My son, daughter, nephew wants to know about Bitcoin

As you live in a joint family and several members of your family are involved in cryptocurrency and your work is always laptop and mobile related so when you work with laptops and mobiles the kids get interested in what you do. Because children are endlessly curious. But as you said every child in your family is primary level and since Bitcoin and other digital currencies are totally banned in your country, I would tell you that there is no need to introduce cryptocurrencies to your children so soon, when they grow up you should introduce these to them Introduce the topic.

Bitcoin is no longer something you will hide from your family members,brothers,sisters,sons and daughters because it is a lifetime promising job that will make you rich for ever.That is why there is need to start telling your household member to have the awareness and know more about Bitcoin so that they can start investing in it and be part of the rich family.
They may have heard of Bitcoin from other person,and will want to confirm from you whether it really exist,or whether it is really the way people say it is.Therefore,it is very good to teach them when they come asking about it.

I don't think it's a bad idea to educate your children about it since it's your choice and going to be your decision as a parent, but the main thing that I think that would be beneficial to focus on is why your family is working with cryptocurrency use when it's banned in your country. Do you think you can get in trouble knowing that idea? Would you want to bear that with your children? I don't think it's a good idea knowing that it's banned. Yes, you can educate them about it, but when you are talking about the legality and how it would work, it's definitely going to be a battle.

There are many legal people/police around us if they get any information about Bitcoin from the mouth of children then our elder family members will face many problems.

I think it's better that you don't involve them if you guys are on the verge of getting in trouble.

I cannot imagine living this life working on a certain thing that is considered illegal in one’s country. Maybe for now your family will be safe as no one has reported it yet, but if someone in your neighborhood will suspect that your family is still working on bitcoin, I guess your family will surely be in trouble. So my advice is that never teach the children for now as they can be very honest when asked by the officers roving around if your family is really into bitcoin.
