now I have a child and my child is still small, of course the bigger my child is, the living expenses will also be greater.
First, concentrate on your child and his/her expenses. Bitcoin investment is not a big deal at the moment as it can happen after some years. Invest whenever you have less liability in your life in Bitcoin. Please understand you only need to invest what you can afford. At moment you cannot! Please focus on your child first and later think about Bitcoin.
so I plan to buy bitcoin and will invest in bitcoin for the long term, with the intention of paying for my children in the future, such as for school capital and my child's future marriage.
but I am also aware of the risks of investing in bitcoin, but I personally am ready for the risk of investing in bitcoin.
Buy Bitcoin if you can afford to lose your money in the sense that the price is very volatile. If you are in an emergency situation then the buying price as in when you bought would not be the selling price you expected. This is a global market and you have to be patient if you intend to buy Bitcoin. Some of us have been holding our patience for a few years now.
