Like every parents want to leave something for children for their future.
Which investment is safe?
Bitcoin?
Stocks?
Real Estate?
If your plan is to invest money for the future of your children, like their education or even a property it is better to choose something that is not as risky as bitcoin, I know that the profits that you can get with it are incredible, but are you willing to gamble the future of your children in bitcoin? I don't have any children that is why I can take more risks than the majority of people, but once you have children you need to take safer choices.
All of them are ok if you can. The aim is to save something for children and doesnt matter cash, bitcoin, property or stock. I want to earn first from bitcoin and then buy some property for my family so that will be able to have their own house in the future and the best thing is to start some regular business, so that children will be financially safe.
Saving something for them is better than not saving anything for them and spending all your money in your daily life. If you save fiat money, the power of that money will be very low after years due to inflation. If you save bitcoin or ether, this will be much more valuable in the future for your children.
