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.
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.
I want to know your opinion?
It sounds like a reasonable plan. Do not keep the coins on any exchange though, preferably use some type of cold storage since computers can be compromised also. It certainly sounds like you have the right time frame, not days, weeks, or months, but years. Depending on what country you are located and the potential amount of value involved later, remember to consider that some places will impose gift taxes to larger amounts so gifting now vs gifting later (post-appreciation) could be smart.
