The first reason why cash is very useful is that it makes me safe form robbery. Many people may think that plunder always happens with cash only, but using credit cards is the most loss when it is stolen by a thief. For example, if have cash and it is stolen by a thief, I just lose my money in my bag only. Therefore, I don’t think over about my money because I just lose that money and I will not lose more my money. On the other hand, if I use credit card, and it is stolen by a thief, I will not lose my money in my credit card only because the thieves may swipe my credit card over the money that I have. For this reason, it gives me a lot of debt. With traditional, using cash is safer than using credit cards.
