Pressure them and do not hesitate to teach them about Bitcoin because they are your kids and even though they do not see the future in Bitcoin, make it your responsibility to make them see the future because as Bitcoin becomes more successful in the future and they are not among those benefitting from this, you will blame yourself for not putting in enough efforts. Our children are our responsibility and we owe it to them to make their future less stressful as ours was and for them to have a better future. There are many investments that you can teach them about but always put Bitcoin first. During the time they are still kids, you can be less strick on them but when they come of age, do the needful by preparing them for a better future
If you think you need to take responsibility for your children's future and need to prepare a good future for them, you should not force or pressure them. Don't do that because once they don't like it and you force them, the result will only be negative.
According to some studies, forcing children to do things they don't like will have consequences such as affecting their psychology, health and causing them to lose confidence, self-esteem...thereby limiting their personal development. Would you want your child to be in that situation?
I guess you don't have children and don't know how to take care of them properly, right? Because as responsible parents, we just need to provide our children with all the necessary knowledge, suggest them the best and let them choose according to their preferences.
