So I have 2 cousins. One of them doesn't save and is a huge spender while the other is a saver and spends only once a year. So would bitcoin be a good way to teach them about saving? Since, mining bitcoin is the only way to make alot of bitcoin, I would use a alt wallet to show them what happens if you spend and don't save. What do you think?
If you think that is good for your two cousins, go ahead. As long they know how to do it. Think an easy way to understand it. For example, create or search some games that related to cryptocurrency, you are not only teaching them to how to save money, you also show them the importance of the money. You must give them a clarification about how the value changes or move and how unstable their value is.
