Saving money does not always have to be in large amounts and done every month, especially for small traders such as street vendors etc. who can only make daily profits. Especially the purpose of saving is to improve discipline and a frugal lifestyle, so that they are expected to be able to manage money better, many people save from a nominal $ 1 or even less which is stored in a safe or piggy bank which is done every day. Periodically maybe every 2-3 weeks they can transfer to their bank account. What do you think?
