I want to know your opinion?
You are aware of the risks of investing in bitcoin, and you are willing to accept it, there is no reason to stop this plan, it will be a great plan. If we compare bitcoin savings with fiat savings, it is clear that bitcoin is more profitable.
But I still want to remind you investing in bitcoin is very risky, and this is the money that you will save for your child, which means your child's future depends on the growth of bitcoin. Make sure that later, if this investment fails, you still have another good plan for your child.
