So I'm not those last moment type of people i always keep sufficient savings. Currently the money i have in bank will be sufficient for me to live in my home country for 4-6 months including ticket fare. And 1-2 months in foreign countries. I also have funds in bitcoin and few alts so that will also help.
Its always good to have an habit of saving money either in bitcoins or in fiat as it will take care of you in emergency situation and you don't need to borrow money from your friends or family as your savings will take care of you if you need money desperately.
yes that is good to have habit of saving money, but i think there should be a limit of saving money while the rest of the money should be invest in bitcoin trading. because through trading we can increase the amount of our money, while by saving it for a long long time there are more chances that its value will decrease.
It should be balance, you save money not only for your possible expenses in the future but also for investment, that way you can expect your money will grow but one must need to take risk if he wants to invest. That is possible if you have a good savings because you are free to allocate a certain amount that you can afford to lose.
