I guess having financial stability is great importance. The crypto currency is not primary business or way of income for most of the people/investors here. So ideally if you want to make investment somewhere then financial money management system does says that you should look after the expenses, the money in and out of your life per month basis. If you get some amount in your savings and some amount still left over after those calculation then you should be risking that money into other stuff like crypto trading with your free mind.
