You might live in a country, where it is not so common to bring your money to the bank or you don’t tend to trust the banks. Well, it is possible to open bank accounts overseas in trustful jurisdictions. For example in Europe, banks guarantee for 100.000€ of savings, even if they go bankrupt. That is ok for the beginning. Not sure about the US, but I guess it is similar to EU. If you have savings in the bank, you can earn an interest on this amount. It is not much, but better than nothing.
