I guess this is a strategy for someone who wants to invest on Bitcoin for a long term but is scared of waiting for too long.
So many persons will want to invest on Bitcoin for a long term but they end up find it difficult to have the patience on their investment and wants an instant shoot up of Bitcoin price,in other for them to sell and make profit,they end up been disappointed when it doesn't go as they wanted it since they don't understand the cyclic movement of Bitcoin. They end up procrastinating they will invest and some that have already invested will get fustrated when Bitcoin is in it bear market by selling their bitcoin.
My suggestion to these set of people is that we should invest on Bitcoin for our children from infantry to teenage. In my country people starts planing for the future of their children from the moment the child is put to bed. Family and well wishers gives money to the child when they come to visit the new born baby to express their happiness for what God has done. Some parents the moment they give birth to a child they open a bank account for the child so that every month from their income they put some fraction of money to the child's account. Some money been given to the child during his birthday celebrations and other ceremonies or visit they always put it into the child's account in other to secure the child's future.
When this child becomes a teen in high school this money must have accumulated to a reasonable amount which is used to support the child to either further his education,start up a trade or learn a skill. Fiat currency is fast depreciating because of inflation, why don't you buy Bitcoin Holdings for your child from infant and do all his savings in Bitcoin so that by the time the child becomes a teenager, Bitcoin price might have hit $500k and above. This way you can have a long term holdings in Bitcoin.
What is your opinion on my suggestion, is it a guarantee for the child's future and will enable you to benefit from Bitcoin ?

OP thanks for representing what I've been doing these few months, even though I've started it for myself. But now my wife is pregnant and the first month at that time I have started saving with Bitcoin. The goal that I do is that the Bitcoin savings must be collected until he grows up. I do this for a better life in the future. It will be quite a long journey until he is born and grows up. Bitcoin will accompany every journey. So far I have been consistent every month with the spirit of saving Bitcoin. All planning is carried out carefully starting from securing the key and everything related to accessing it is really guarded. Including having a guardian if one day I can't supervise the growth and development of the child.
