I think that this is the best thing to do if you have a family and you want to secure your family. If you want to have a great future then you should save bitcoin for your children and you should do a lot of work before you reach to the point that you can relax and feel safe with your savings because if you will become greedy in spending money from bitcoin then the savings will not happen because the problem is from you.
It is a nice idea that we save bitcoin for our kids because as what we have experience for the past months almost 1 bitcoin really increase it's price nearly to 1 million.How much more if we save bitcoin for our children and stocked it for how many years.Maybe it's price will rise to 5 to 10 million in equivalent to 1 bitcoin.If this will happen our children have a secured future to extend our wealth and creates a big name to our society and make us famous for one of the rich family because of bitcoin.
So for everyone who have clearly earned bitcoin try to think what I have said for the future of your children.
