Reducing what you spend on can make more money available to spend on investing in bitcoins. But when reducing your expenses, do not remove important needs from what you need to spend money on because you are trying to save money to invest in bitcoins. See a doctor when you need to, dress and eat well. If you neglect yourself good healthcare after you have denied yourself some comfort, if you fall sick, you may die and leave all your bitcoins lost if you did not plan a way to pass it on to someone. Take care of yourself as you try to invest.
